| CVE-2026-77819 | 2 Ibm, Langflow | 2 Langflow Oss, Langflow | 2026-10-30 | 6.5 Medium |
| IBM Langflow OSS 1.0.0 through 1.12.3 could allow a remote authenticated attacker to overwrite arbitrary files due to improper limitation of a pathname to a restricted directory. | ||||
| CVE-2026-99091 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-30 | 3.6 Low |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Fix status of pending commands flushed on power off cmd_complete_rsp() receives a struct cmd_lookup and, for a pending command that has no cmd_complete callback, falls through to cmd_status_rsp(cmd, data). cmd_status_rsp() reads data as a u8 *, so the status sent comes from the first byte of match->sk's representation, not from match->mgmt_status. commit f53e1c9c726d ("Bluetooth: MGMT: Fix possible crash on mgmt_index_removed") changed the callers' data from &status to &match and updated the cmd_complete branch to match->mgmt_status, but left the fall-through passing data unchanged. In mgmt_index_removed() match->sk is NULL, so every such command is answered with status 0x00 (Success) instead of MGMT_STATUS_INVALID_INDEX. In __mgmt_power_off() it is NULL too, unless a Set Powered command was pending: then settings_rsp() has stored that command's socket in match->sk, and the byte sent comes from the socket pointer. Either way the status the caller set, MGMT_STATUS_NOT_POWERED (or MGMT_STATUS_INVALID_INDEX when the device is being unregistered), is lost. Pass the status the callers set. This was seen on a QCA9377 laptop: bluetoothd's Start Discovery, pending when the adapter was powered off, was answered with Command Status 0x00 and no parameters, and bluetoothd 5.72 crashed on the zero-length success. BlueZ master has since added the length check on that path ("adapter: Fix crash on short start discovery reply", BlueZ a734b06059cb), but userspace should still be told Not Powered, not Success. Tested on Ubuntu 7.0.0-31 with a virtual controller (hci_vhci): power off is held in HCI Write Scan Enable while a Start Discovery is submitted, and the flush answers it with status 0x00 before this change and 0x0f (Not Powered) after. | ||||
| CVE-2026-99077 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-30 | 7.4 High |
| 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-2026-99071 | 1 Linux | 2 Linux, Linux Kernel | 2026-10-30 | 4.1 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ipv4: do not warn on route notification size race Commit 680aea08e78c ("net: ipv4: Emit notification when fib hardware flags are changed") added asynchronous route notifications for hardware flag changes. fib_alias_hw_flags_set() sizes the skb with fib_nlmsg_size() and later fills it with fib_dump_info() while holding only RCU. With nexthop compatibility mode enabled, a concurrent replacement can grow the group between these independent snapshots. fib_dump_info() can then legitimately return -EMSGSIZE, so the warning does not prove a sizing bug. Remove the warning. The existing error path still frees the skb and reports the error to listeners. | ||||
| CVE-2026-90991 | 2 Ibm, Langflow | 2 Langflow Oss, Langflow | 2026-10-30 | 6.5 Medium |

| CVE-2026-92389 | 1 Curl | 1 Curl | 2026-10-30 | 8.1 High |
| libcurl's TFTP state machine fails to validate state transitions against the requested transfer direction, accepting opening server responses for both reads and writes interchangeably. A malicious TFTP server can respond to a download request in a way that forces the client into transmit mode, prompting libcurl to consume and transmit data from the handle's persistent `CURLOPT_READDATA` pointer - including data remaining from unrelated prior operations, such as an HTTP POST request executed on a reused handle. | ||||
| CVE-2026-92388 | 1 Curl | 1 Curl | 2026-10-30 | 9.1 Critical |
| When an FTP wildcard `LIST` operation fails, libcurl omits the restoration path meant for successful listings, leaving the write callback set to the internal listing parser and the write callback data pointing directly to the easy handle. Subsequent reuse of this handle triggers an immediate crash, and cloning it via `curl_easy_duphandle()` copies this corrupted state into the duplicate. If the original handle is subsequently freed, executing a transfer on the cloned handle causes a heap use-after-free read against the dangling handle reference; alternatively, reusing the original or cloned handle while changing only `CURLOPT_WRITEDATA` (and omitting `CURLOPT_WRITEFUNCTION`) results in type confusion, forcing the internal parser to interpret incoming server response bytes into memory at the application-supplied write data pointer. | ||||
| CVE-2026-85783 | 1 Perl | 1 Crypt::age | 2026-10-30 | 7.5 High |
| Crypt::Age versions before 0.004 for Perl allow CPU exhaustion via an unbounded number of recipient stanzas, each costing an X25519 scalar multiplication in unwrap_file_key. The header parser accepts any number of recipient stanzas, and unwrap_file_key tries every identity against every X25519 stanza. Each attempt runs a scalar multiplication, an HKDF and a ChaCha20-Poly1305 open. The header MAC cannot be checked first, because its key comes from the file key, which only a successful unwrap produces. Each stanza is 98 bytes of attacker-chosen header and buys one scalar multiplication per identity held, and the file is rejected only after every one of them has run. A caller reaches this through decrypt, decrypt_file or decrypt_filehandle whenever it decrypts a file it did not write. | ||||
| CVE-2026-72416 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.3 High |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_compat: ebtables emulation must reject non-bridge targets xtables targets return netfilter verdicts: NF_ACCEPT, NF_DROP, and so on. ebtables targets return incompatible verdicts: EBT_ACCEPT, EBT_DROP, ... We cannot allow fallback to NFPROTO_UNSPEC. ebtables doesn't permit this since 11ff7288beb2 ("netfilter: ebtables: reject non-bridge targets") but that commit missed the nft_compat layer. | ||||
| CVE-2026-43115 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: srcu: Use irq_work to start GP in tiny SRCU Tiny SRCU's srcu_gp_start_if_needed() directly calls schedule_work(), which acquires the workqueue pool->lock. This causes a lockdep splat when call_srcu() is called with a scheduler lock held, due to: call_srcu() [holding pi_lock] srcu_gp_start_if_needed() schedule_work() -> pool->lock workqueue_init() / create_worker() [holding pool->lock] wake_up_process() -> try_to_wake_up() -> pi_lock Also add irq_work_sync() to cleanup_srcu_struct() to prevent a use-after-free if a queued irq_work fires after cleanup begins. Tested with rcutorture SRCU-T and no lockdep warnings. [ Thanks to Boqun for similar fix in patch "rcu: Use an intermediate irq_work to start process_srcu()" ] | ||||
| CVE-2026-31568 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: s390/mm: Add missing secure storage access fixups for donated memory There are special cases where secure storage access exceptions happen in a kernel context for pages that don't have the PG_arch_1 bit set. That bit is set for non-exported guest secure storage (memory) but is absent on storage donated to the Ultravisor since the kernel isn't allowed to export donated pages. Prior to this patch we would try to export the page by calling arch_make_folio_accessible() which would instantly return since the arch bit is absent signifying that the page was already exported and no further action is necessary. This leads to secure storage access exception loops which can never be resolved. With this patch we unconditionally try to export and if that fails we fixup. | ||||
| CVE-2026-113812 | 2026-10-30 | 9.1 Critical | ||
| Mozilla::CA versions before 20261020 for Perl provide a CA certificate bundle containing a root linked to compromised intermediates. The bundle includes "emSign ECC Root CA - G3", which provides a trust path for intermediate certificates whose private keys are publicly available. An attacker able to intercept or redirect client traffic may use these keys to impersonate a TLS server. LWP, HTTP::Tiny and other clients normally use IO::Socket::SSL, which looks for CA certificates in OpenSSL's default locations before falling back to Mozilla::CA. Configuration and environment variables can override this selection. Users should check which CA store their client uses. If it uses the system store, check for and install the operating system vendor's updates for this incident. | ||||

| CVE-2026-113030 | 1 Google | 1 Chrome | 2026-10-30 | 8.8 High |
| Improper access control in V8 in Google Chrome prior to 156.0.8078.47 allowed a remote attacker to potentially bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium) | ||||
| CVE-2026-112202 | 2026-10-30 | 6.5 Medium | ||
| Imager::File::GIF versions before 1.006 for Perl allow out-of-bounds reads when consolidating GIF images. With `gif_consolidate => 1`, palette indices from the image are used without checking the colour table's bounds. The i_readgif_low routine reads beyond the heap allocation and copies the bytes into output pixels. The default GIF reader is not affected. The same code ships bundled in the Imager distribution. An attacker supplying a crafted GIF can disclose adjacent heap memory through the decoded output and may crash the process. | ||||
| CVE-2026-111943 | 2 Go Standard Library, Redhat | 3 Crypto/x509, Enterprise Linux, Hummingbird | 2026-10-30 | 6.8 Medium |
| On most platforms, Go uses the given system root certificates. However, in some narrower cases, the system trust stores may not be updated without further action. To defend against the narrower set of cases that may remain affected, a denylist was added in crypto/x509 to return an error when calling Verify with any of the known intermediate certificates that are no longer considered to be trustworthy. | ||||
| CVE-2026-111879 | 1 Perl5-dbi | 1 Dbi | 2026-10-30 | 6.5 Medium |
| DBI versions before 1.656 for Perl hang on a later open of a DBD::DBM table because a failed open_data does not release the table's lock. open_data creates the table's lock file and takes an exclusive flock on it for a CREATE, before the checks that can croak: a dbm_mldbm value that is not a module name, a failing tie, or a missing data file. The croak unwinds before the table object is blessed, so nothing releases the lock, and the meta data holding the open descriptor stays cached on the database handle. The dbm_mldbm and dbm_type values come from the DSN or the connect attributes, so a caller that chooses the serializer or the storage backend can trigger the failure. The flock has no timeout, so a later open of that table (even through a separate database handle) blocks for as long as the handle holding the stale lock lives, in the same process or any other. | ||||
| CVE-2026-108518 | 1 Perl5-dbi | 1 Dbi | 2026-10-30 | 2.9 Low |
| DBI versions before 1.656 for Perl crash via type confusion in dbi_profile when a database handle is destroyed under a Profile Path with an {attr} element. An {attr} element names a database handle attribute, which dbi_profile reads from the handle's inner hash. It expects the inner handle as a reference and dereferences it, but a handle that is being destroyed hands back the inner hash itself, so the dereference yields the hash's bucket array. A type check on that pointer usually fails and the call goes unprofiled. When the memory it addresses passes the check, the attribute lookup dereferences a NULL or invalid pointer and the process dies on SIGSEGV. The Path is set by the application, by the Profile handle attribute, or by the DBI_PROFILE environment variable, so `DBI_PROFILE={ImplementorClass}` can crash an unmodified program. | ||||
| CVE-2026-119601 | 1 Afflib Project | 1 Afflib | 2026-10-30 | 6.1 Medium |
| AFFLIB through 3.7.22 contains a heap out-of-bounds write vulnerability in af_get_page() that allows attackers to corrupt heap memory by supplying crafted AFF images with mismatched page and sector sizes. Attackers can set a page size larger than and not a multiple of the sector size, causing the sector zero-fill loop to write past the buffer and crash forensic tools. | ||||
| CVE-2025-40328 | 1 Linux | 1 Linux Kernel | 2026-10-30 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential UAF in smb2_close_cached_fid() find_or_create_cached_dir() could grab a new reference after kref_put() had seen the refcount drop to zero but before cfid_list_lock is acquired in smb2_close_cached_fid(), leading to use-after-free. Switch to kref_put_lock() so cfid_release() is called with cfid_list_lock held, closing that gap. | ||||
