| CVE-2026-99061 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: fix P2P device removal race in brcmf_detach() When the driver is removed while the user space process that created the P2P device (e.g. wpa_supplicant) is still exiting, the P2P device interface is removed twice and the kernel crashes. The two paths are: - wpa_supplicant, on exit, sends NL80211_CMD_DEL_INTERFACE for the P2P device. nl80211_del_interface() holds RTNL and the wiphy mutex and calls brcmf_p2p_del_vif(), which disables discovery and waits up to 1.5 s for BRCMF_E_IF_DEL. Then it calls brcmf_remove_interface(), which unregisters the wdev and frees the vif and the ifp. - brcmf_detach() sets the bus down, so BRCMF_E_IF_DEL never arrives, and calls brcmf_remove_interface(ifp, false) for the same ifp. brcmf_p2p_ifp_removed() reads ifp->vif and then blocks on rtnl_lock(). When brcmf_p2p_del_vif() releases RTNL, it calls cfg80211_unregister_wdev() on the wdev that was already unregistered and freed. The second list_del_rcu() of wdev->list faults on LIST_POISON2: brcmfmac: brcmf_p2p_del_vif delete P2P vif brcmfmac: brcmf_p2p_deinit_discovery enter brcmfmac: brcmf_p2p_del_vif P2P: GO_NEG_PHASE status cleared brcmfmac: brcmf_detach Enter brcmfmac: brcmf_bus_change_state 1 -> 0 brcmfmac: brcmf_remove_interface Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_del_if Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_p2p_ifp_removed P2P: device interface removed [1.5 s later, brcmf_p2p_del_vif() timed out] brcmfmac: brcmf_remove_interface Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_del_if Enter, bsscfgidx=1, ifidx=0 brcmfmac: brcmf_p2p_ifp_removed P2P: device interface removed Unable to handle kernel paging request at virtual address dead000000000122 Internal error: Oops: 96000044 [#1] PREEMPT_RT SMP pc : _cfg80211_unregister_wdev+0x6c/0x264 [cfg80211] Call trace: _cfg80211_unregister_wdev+0x6c/0x264 [cfg80211] cfg80211_unregister_wdev+0x10/0x1c [cfg80211] brcmf_p2p_ifp_removed+0x84/0xb0 [brcmfmac] brcmf_remove_interface+0x1f4/0x254 [brcmfmac] brcmf_detach+0x88/0x180 [brcmfmac] brcmf_sdio_remove+0x90/0x7b0 [brcmfmac] brcmf_sdiod_remove+0x20/0xa0 [brcmfmac] brcmf_ops_sdio_remove+0xbc/0x12c [brcmfmac] sdio_bus_remove+0x38/0x144 device_release_driver_internal+0x1e8/0x2c0 device_release_driver+0x14/0x20 brcmf_sdio_bus_remove+0x2c/0x40 [brcmfmac] brcmf_fwvid_unregister_vendor+0xd8/0x170 [brcmfmac] __exit_compat+0x18/0x418 [brcmfmac_cyw] __arm64_sys_delete_module+0x1ac/0x244 The log was taken with debug=0x406 on an i.MX 8M Plus board with a CYW55513 (Sona IF513) on SDIO. The driver is the Ezurio backport of brcmfmac from v6.18.22 on a 5.4-rt kernel. The code involved is the same in mainline. To reproduce: 1. Start wpa_supplicant on wlan0 and let it associate. It creates the P2P device (iw dev shows "type P2P-device"). 2. Stop wpa_supplicant and remove the driver without waiting for wpa_supplicant to exit: kill $(pidof wpa_supplicant) rmmod brcmfmac_cyw brcmfmac The crash is reproducible on that board. For the interface without a netdev (the P2P device), take RTNL and the wiphy mutex in brcmf_detach() before reading iflist, and remove it with locked=true. If brcmf_p2p_del_vif() runs first, brcmf_detach() finds the slot empty. If brcmf_detach() runs first, nl80211 does not find the wdev any more. The interfaces with a netdev are removed as before, because brcmf_del_if() takes RTNL on its own for the primary interface. | ||||
| CVE-2026-99062 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: account only unread bytes in read_skb() After a partial stream receive, rx_bytes tracks the unread suffix while buf_used and peer credit still cover the whole packet. virtio_transport_read_skb() dequeues that packet but passes pkt_len for both counters, underflowing rx_bytes. On a connected CID_LOCAL stream with an SK_SKB verdict, a 40-byte read from a 100-byte packet made SIOCINQ report -40, an empty recv return ELOOP, and poll report the empty socket readable. After verdict detach, receiving 40 bytes wrapped the counter to zero and hid those queued bytes until one more byte arrived. The fixed run kept the counter balanced and exposed all queued data immediately. This was found during an LLM-assisted manual source audit of VSOCK receive accounting while re-evaluating virtio_transport_read_skb() after CVE-2024-50169. Subtract only skb->len minus the VSOCK offset from rx_bytes. Retain the full packet length for buf_used and peer credit. | ||||
| CVE-2026-99064 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cipso: adjust cached option offsets when removing CIPSO cipso_v4_skbuff_delattr() removes the CIPSO bytes but does not adjust cached offsets for options that follow them. For example, with a valid 10-byte CIPSO option followed by a seven-byte RR option, parsing records rr at offset 30. Removing CIPSO moves RR to offset 20, while the cached offset remains 30. Consumers such as ip_forward_options() and __ip_options_echo() then access the wrong bytes; the latter may interpret packet data as the option length and copy it into fixed-size option storage. Mirror cipso_v4_delopt() and subtract cipso_len from the srr, rr, ts and router_alert offsets when they follow CIPSO. cipso_len is the distance the first memmove() shifts those options. The later header move and network-header reset relocate the bytes and their offset base together. | ||||
| CVE-2026-99065 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Handle cpu hotplug race in guarantee_active_cpus() With commit 2125c0034c5d ("cgroup/cpuset: Make cpuset hotplug processing synchronous"), the cpuset hotplug operation becomes synchronous. That commit also removes the code that handles race between cpuset_hotplug_work and cpu hotplug notifier with the assumption that race is now gone. Later commit 7a0aabd9ce69 ("cgroup/cpuset: Always use cpu_active_mask") updates the cpuset code to always use cpu_active_mask instead of cpu_online_mask in some places including guarantee_online_cpus() which is renamed to guarantee_active_cpus() in that commit. In the case of CPU offline operation, cpu_active_mask is updated first in sched_cpu_deactivate() to remove the offline CPU before cpuset_handle_hotplug() is called to update the effective_cpus of the affected cpusets. The cpu_online_mask is updated after that near the end of the offline operation to remove the offline CPU. As a result, the race comes back and the top cpuset may not have any active CPU leading to NULL pointer dereference during the race window when guarantee_active_cpus() is called after cpu_active_mask is updated to remove the CPU to be torn down but before cpuset_handle_hotplug() is able to properly update the effective_cpus of the top cpuset. Fix this by adding back the NULL cs check to avoid this problem. | ||||
| CVE-2026-99066 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: can: dev: init_can_skb(): restore skb header initialization Commit 9f10374bb024 ("can: remove private CAN skb headroom infrastructure") removed the skb_reset_mac_header()/skb_reset_network_header()/ skb_reset_transport_header() calls from init_can_skb(). As a result, RX skbs from alloc_can_skb() and friends again carry mac_header = 0xFFFF. When such an skb reaches packet_rcv_spkt() (SOCK_PACKET), the push length calculation overflows and triggers skb_under_panic -> kernel BUG -> full machine panic. The same issue was originally reported in 2014 on linux-can and fixed by commit 969439016d2c ("can: add missing initialisations in CAN related skbuffs"). packet_rcv_spkt() itself has never been hardened: only packet_rcv() and tpacket_rcv() gained dev_has_header() checks in commit d549699048b4 ("net/packet: fix packet receive on L3 devices without visible hard header"). | ||||
| CVE-2026-99067 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: scrub: fix local_root reference leak in scrub_print_warning_inode() When paths_from_inode() fails, scrub_print_warning_inode() jumps to err without dropping the reference taken by btrfs_get_fs_root(), leaking a reference to the root every time path resolution fails while printing scrub warnings. Every other error and success path of the function drops the reference. Drop the reference on the paths_from_inode() failure path too. | ||||
| CVE-2026-99069 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Input: ati_remote2 - fix type confusion in device attribute handlers Previously, the channel_mask and mode_mask attributes were registered on the parent usb_device via sysfs_create_group(). When commit b20d6bf8014b ("Input: ati-remote2 - use driver core to instantiate device attributes") converted the driver to let the driver core manage them via dev_groups in struct usb_driver, the attributes moved to the bound usb_interface devices, but the show and store callbacks were not updated accordingly. As a result, the callbacks still invoked to_usb_device() on a device pointer belonging to a struct usb_interface, producing an invalid usb_device pointer. Use to_usb_interface() directly in the attribute handlers to obtain the interface and its driver data. | ||||
| CVE-2026-99075 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: rust_binder: reschedule node refcount update on thread exit When a thread exits via BINDER_THREAD_EXIT, its pending work items are cancelled. If a thread exits while holding a pending node refcount increment (e.g. pushed as deferred work to that thread), the refcount increment was previously dropped because Node::cancel() and NodeWrapper::cancel() were no-ops. Dropping the refcount update leaves the node's delivery state and count state desynchronized, and userspace will not receive the notification, which can cause the node to never be freed from the process's nodes tree when all external references are dropped. Fix this by implementing DeliverToRead::cancel() for Node and NodeWrapper to move the pending refcount update to the process's work queue on thread exit so another thread can deliver it to userspace. | ||||
| CVE-2026-99077 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ipv4: udp: Create exceptions before socket matching Currently, when ICMP Fragmentation Needed and Redirect Message packets are locally delivered and quote a UDP packet, a FIB nexthop exception (FNHE) is only created if the kernel can match the UDP packet to an existing socket. This behavior allows off-path attackers to conduct a side-channel attack on the FNHE cache in order to discover the ephemeral port used by a connected UDP socket. Commit 6457378fe796 ("ipv4: use siphash instead of Jenkins in fnhe_hashfun()") and commit 67d6d681e15b ("ipv4: make exception cache less predictible") tried to mitigate such attacks by making it harder for attackers to discover hash collisions in the FNHE cache and by randomizing the number of exceptions a hash bucket can hold, respectively. Unfortunately, both of the mitigations can be bypassed. Instead, mitigate such attacks by always creating a FNHE, even before trying to find a matching socket. Do that by calling ipv4_update_pmtu() and ipv4_redirect(), the helpers used when the quoted packet did not originate from a socket. This means that guesses (right or wrong) from an off-path attacker will always result in a FNHE being created or updated in the cache that the attacker can observe. Pass an oif of 0, in a similar fashion to icmp_err(). This is also the oif used by the socket path for sockets that are not bound to a device. Note that this does not allow attackers to create FNHEs that they could not create before, as both helpers can already be reached with little to no validation. For example, by sending an ICMP error that quotes an ICMP Echo Reply or one that quotes a UDP source port that matches a wildcard socket. Also note that in the good case (matched socket) the above scheme comes at the cost of an extra route lookup, as the no socket helpers perform their own lookup before the one performed by ipv4_sk_update_pmtu() / ipv4_sk_redirect(). When the two resolve to different nexthops, it also results in two exceptions being created for the same destination IP. One in the FNHE cache of the nexthop resolved by the no socket helpers and another in the FNHE cache of the nexthop used by the socket. | ||||
| CVE-2026-99078 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent stale XSK buffer release on MPWQE refill retry With AF_XDP on a striding RQ, mlx5e defers releasing XSK buffers until an MPWQE is refilled. If XSK allocation then returns -ENOMEM, actual_wq_head is not advanced and a later NAPI poll retries the same WQE. mlx5e_free_rx_mpwqe() leaves each released slot marked as releasable. On retry it can therefore call xsk_buff_free() again through stale pointers after the frames have returned to the XSK pool and been reallocated. Set all skip_release_bitmap bits in the common error path of mlx5e_xsk_alloc_rx_mpwqe(). This matches mlx5e_alloc_rx_mpwqe(). A successful allocation already clears the bitmap after replacing every buffer, so retries become idempotent without changing the success path. Fault injection forced three consecutive failures for one selected MPWQE. Both an early allocation failure and a partial 8-of-16-buffer unwind released the original 16 XSK buffers only once. Each error left a full bitmap, the following NAPI retry skipped the release, and a later successful allocation cleared it. A 20-second AF_XDP zero-copy pressure run exercised 1,575,262 buffer allocation failures without invalid descriptors, WQE errors, or kernel warnings. | ||||
| CVE-2026-99079 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Prevent stale XSK buffer release on refill retry When an XDP redirect to an AF_XDP socket fails because its RX ring is full, the XSK core frees the buffer. During the subsequent batched refill of a legacy cyclic RQ, mlx5e also releases the WQE's XSK buffer before allocating a replacement. If that refill succeeds only partially, a WQE left without a replacement retains its old buffer pointer. The buffer can meanwhile be allocated to another WQE. A later refill retry can then free the live buffer through the stale pointer and publish the same UMEM frame twice. Mark the WQE as released immediately after the driver-side free. The flag is already cleared when a replacement buffer is assigned, so refill retries no longer release stale pointers. The failure is silent and produces no kernel warning or splat. A standalone legacy cyclic-RQ zero-copy libxsk reproducer, using 64-byte UDP traffic offered at 12 Mpps, detected it: stock stopped after 2,854,914 packets in 4.094 seconds, with 4,542 xdp_rx_ring_full events and 64 ownership/double-publication errors. With this change it processed 356,904,225 packets in 30 seconds despite 571,405 xdp_rx_ring_full events, with no ownership or data errors. | ||||
| CVE-2026-99080 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: fs: Free any excess xarray nodes in clear_inode() For many years we've had a hard to hit leak of xarray nodes. Hugh documented it well in commit 786b31121a2c. Recently people and syzbot have found ways to force it to happen with madvise. Rather than fix the leaks where they happen, just call xa_destroy() which has the side-effect of cycling the i_pages lock. | ||||
| CVE-2026-99009 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: connect the session socket without rfcomm_mutex An RFCOMM connect() issued while a BR/EDR link is being authenticated makes lockdep report a circular dependency, and the reported cycle is a real AB/BA between rfcomm_mutex and hdev->lock. rfcomm_security_cfm() is called from the HCI event path, which already holds hdev->lock: hci_rx_work() hci_event_packet() hci_cc_read_enc_key_size() [hdev->lock] hci_encrypt_cfm() [hci_cb_list_lock] rfcomm_security_cfm() [rfcomm_mutex] while an RFCOMM connect() from userspace takes the same two locks the other way round: rfcomm_sock_connect() rfcomm_dlc_open() [rfcomm_mutex] __rfcomm_dlc_open() rfcomm_session_create() kernel_connect() l2cap_sock_connect() l2cap_chan_connect() [hdev->lock] WARNING: possible circular locking dependency detected kworker/u131:1/1128 is trying to acquire lock: rfcomm_mutex, at: rfcomm_security_cfm+0x31/0x3e0 [rfcomm] but task is already holding lock: hci_cb_list_lock, at: hci_cc_read_enc_key_size+0x1d2/0xcc0 Chain exists of: rfcomm_mutex --> &hdev->lock --> hci_cb_list_lock hci_auth_complete_evt() and hci_encrypt_change_evt() reach the callback the same way. Both orders have to be seen in the same boot, which is why a BR/EDR connection alone is not enough to show it: a session set up by the remote side is created by rfcomm_accept_connection() in krfcommd, which calls kernel_accept() and never takes hdev->lock under rfcomm_mutex. Connecting a device that authenticates and encrypts the link and then calling connect() on an RFCOMM socket towards any address - the connect does not have to succeed, the order is recorded before the page timeout - reports it every time. Only the session socket has to be connected with the lock held, and it does not: nothing else can see the socket before it is put on the session list. So connect it first and take rfcomm_mutex afterwards, which removes the rfcomm_mutex -> hdev->lock order for good, rather than keeping the HCI event path out of rfcomm_mutex. rfcomm_session_create() becomes rfcomm_session_connect(), which returns the connected socket without touching the session list, and rfcomm_dlc_open() adds the session once it holds the lock again. If another opener added a session for the same pair while this socket was connecting, that session is used and this socket is dropped. __rfcomm_dlc_open() now takes the session it should use, and its state check runs after the lock is re-acquired, so a DLC that was opened or closed in the meantime is still handled. Over an existing ACL link the connection can complete before the session reaches the list, and the wakeup from the socket callback is then lost, so krfcommd is woken once the session is visible. Connecting without the lock opens a window in which the socket can be closed. The DLC is not on a session yet, so rfcomm_dlc_close() finds nothing to do and returns without touching it, and rfcomm_dlc_open() would then attach a DLC whose owner is gone. rfcomm_dlc_close() now marks such a DLC with RFCOMM_CLOSED, and rfcomm_dlc_open() checks the mark once it holds rfcomm_mutex again and drops the socket instead of attaching the DLC. The mark is cleared when an open starts, so a DLC that is reused is not affected. This covers both callers of rfcomm_dlc_open(), the socket and the tty layer. | ||||
| CVE-2026-99010 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: free the skb when the DLC has no owner rfcomm_recv_data() hands the skb to d->data_ready() and returns 0 without freeing it, so the callback owns the skb from that point on. The tty implementation frees it when the DLC has been detached from its device: static void rfcomm_dev_data_ready(struct rfcomm_dlc *dlc, struct sk_buff *skb) { struct rfcomm_dev *dev = dlc->owner; if (!dev) { kfree_skb(skb); return; } The socket implementation returns without freeing it, and the skb is leaked. A connected DLC can have no owner: rfcomm_sock_destruct() clears d->owner, while the DLC itself stays on the session until it is closed. Data frames that arrive in that window still find d->state == BT_CONNECTED in rfcomm_recv_data() and are handed to the callback, one leaked skb each. The leak does not stop on its own either. The remote runs out of credits only once RFCOMM_RX_THROTTLED is set, and for a socket the only place that sets it is rfcomm_sk_data_ready() itself, below the return. rfcomm_process_dlcs() keeps granting credits, so the remote keeps sending and the leak keeps growing. Free the skb, as the tty side does. | ||||

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Serialize concurrent connect calls iso_sock_connect() checks the socket state before taking the socket lock and drops the lock again before setting up a connection. Two callers can both pass the admission check while the socket is open or bound. Caller A can copy its destination for route selection, then caller B can replace the socket destination before A binds or connects the CIS. A then uses B's destination with the route selected for its own request. B can also proceed after A attaches a connection and sets BT_CONNECT. For deferred BIS setup, B can bind a second BIS and overwrite iso_pi(sk)->conn, leaving the first connection's reference and conn->sk back-pointer stranded. Concurrent CIS connects can likewise replace the socket's connection. Later teardown only detaches the current connection, so a callback on the old connection can race with socket release and access a freed socket.

Keep that flag set across route lookup and connection setup, rejecting another connect with -EBADFD before it can change the destination or attach a connection. Clear the flag after either helper returns, including on failure, so a failed setup can be retried. A separate flag is needed because the socket lock must be released before acquiring the HCI device lock, while BT_CONNECT requires an attached connection. Keep the existing state transitions and the deferred CIS completion through iso_sock_recvmsg(). Reject an existing socket attachment in __iso_chan_add() before taking a new reference or publishing either pointer, so every caller preserves the connection association. Keep the same-socket, same-connection success case for deferred CIS setup. Reject an attached socket before BIS setup so a reusable BIS is not claimed before the attachment is rejected. In CIS setup, reject a different HCI connection before iso_conn_add() and drop the per-attempt HCI hold directly. An unowned iso_conn may still carry another reference after detachment, so its destruction cannot be relied on to release that hold. iso_listen_bis() creates a fresh PA HCI/ISO pair under the device lock, so the temporary iso_conn_put() frees the ISO candidate and drops its HCI hold on rejection. iso_conn_ready() uses a freshly allocated, unpublished child with no connection, making the socket-side rejection unreachable. | ||||

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Reject concurrent BIS listener setup iso_sock_listen() drops the socket lock before calling iso_listen_bis() to preserve the hdev->lock ordering. Two concurrent listen() calls on the same broadcast socket can therefore both observe BT_BOUND. Caller A can attach connA and release the locks, then caller B can acquire them and attach connB before A publishes BT_LISTEN. __iso_chan_add() checks whether connB already has a socket, but not whether the socket already has a connection. The second attachment overwrites iso_pi(sk)->conn, leaking the connA reference and leaving connA->sk intact. Socket teardown follows connB, so later events on connA can cause a stale socket access. Recheck BT_BOUND and require iso_pi(sk)->conn to be NULL after taking both the HCI device and socket locks in iso_listen_bis(). The connection check also covers the interval between attachment and publication of BT_LISTEN. Reject a competing setup with -EBADFD through the existing unlock path before allocating another connection.

| In the Linux kernel, the following vulnerability has been resolved: regulator: tps6594-regulator: Fix n_linear_ranges for TPS65224 BUCK2-4 The TPS65224 BUCK2, BUCK3 and BUCK4 descriptors pass 4 as n_linear_ranges, but tps65224_bucks_2_3_4_ranges[] only has two entries, covering selectors 0x00-0x45. The linear range helpers loop over n_linear_ranges entries, so any lookup of a selector above 0x45 reads past the end of the array and treats whatever follows it as two more ranges. This happens on the normal registration path when the core checks the voltage constraints against every selector. TPS652G1 uses the same descriptors and is affected too. Use ARRAY_SIZE() so the count always matches the table. | ||||

| In the Linux kernel, the following vulnerability has been resolved: regulator: ltc3676: don't read the write-only HRST and CLIRQ registers HRST (0x1e) and CLIRQ (0x1f) are write-only command strobes. Writing HRST triggers a hard reset of the chip and writing CLIRQ clears the interrupt; reading them returns nothing useful, and the read itself fires the command. The result is that a plain register dump resets the board: cat /sys/kernel/debug/regmap/2-003c/registers walks every readable register, hits HRST, and the board reboots. Split the callback back in two so HRST and CLIRQ stay writable but are no longer readable. The readable range is left unchanged (LTC3676_BUCK1 ... LTC3676_IRQSTAT). | ||||

| In the Linux kernel, the following vulnerability has been resolved: power: sequencing: pcie-m2: Fix leaking array from of_regulator_bulk_get_all() of_regulator_bulk_get_all() allocates the consumers array and hands it to the caller, who is expected to free it at an appropriate time. pwrseq-pcie-m2.c never did, leading to a memory leak. Add an explicit kfree() for the consumers array. | ||||
| CVE-2026-99024 | 1 Linux | 1 Linux Kernel | 2026-10-23 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: optee: register TEE devices only once fully initialized optee_probe() called tee_device_register() on both the client and the supplicant device before the rest of struct optee had been initialized. tee_device_register() calls cdev_device_add(), which does two things at once: it creates /dev/tee0 and /dev/teepriv0, and it links the device into the tee class so that class_find_device() can find it. From that moment on the device is reachable both from user space via tee_open() and from kernel space via tee_client_open_context(). The only gate in teedev_open() is tee_device_get(), which merely checks that teedev->desc is non-NULL, which was already set by tee_device_alloc(). Therefore, there is effectively no gate at all. A context opened in that window can run against a struct optee where - optee->call_queue.mutex is not initialized by optee_cq_init() - optee->supp mutex and completions is not initialized by optee_supp_init() - optee->rpmb_dev_mutex is not initialized yet, - the message argument cache is not initialized by optee_shm_arg_cache_init() - optee->ctx is still NULL Any open session or invoke during this window takes uninitialized mutexes and dereferences a NULL pointer. Fix it by moving both tee_device_register() calls down to the point where all of struct optee is set up. [JW: adding fixes and cc] | ||||
