| CVE-2026-43448 | 1 Linux | 1 Linux Kernel | 2026-05-21 | 4.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: nvme-pci: Fix race bug in nvme_poll_irqdisable() In the following scenario, pdev can be disabled between (1) and (3) by (2). This sets pdev->msix_enabled = 0. Then, pci_irq_vector() will return MSI-X IRQ(>15) for (1) whereas return INTx IRQ(<=15) for (2). This causes IRQ warning because it tries to enable INTx IRQ that has never been disabled before. To fix this, save IRQ number into a local variable and ensure disable_irq() and enable_irq() operate on the same IRQ number. Even if pci_free_irq_vectors() frees the IRQ concurrently, disable_irq() and enable_irq() on a stale IRQ number is still valid and safe, and the depth accounting reamins balanced. task 1: nvme_poll_irqdisable() disable_irq(pci_irq_vector(pdev, nvmeq->cq_vector)) ...(1) enable_irq(pci_irq_vector(pdev, nvmeq->cq_vector)) ...(3) task 2: nvme_reset_work() nvme_dev_disable() pdev->msix_enable = 0; ...(2) crash log: ------------[ cut here ]------------ Unbalanced enable for IRQ 10 WARNING: kernel/irq/manage.c:753 at __enable_irq+0x102/0x190 kernel/irq/manage.c:753, CPU#1: kworker/1:0H/26 Modules linked in: CPU: 1 UID: 0 PID: 26 Comm: kworker/1:0H Not tainted 6.19.0-dirty #9 PREEMPT(voluntary) Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.3-0-ga6ed6b701f0a-prebuilt.qemu.org 04/01/2014 Workqueue: kblockd blk_mq_timeout_work RIP: 0010:__enable_irq+0x107/0x190 kernel/irq/manage.c:753 Code: ff df 48 89 fa 48 c1 ea 03 0f b6 14 02 48 89 f8 83 e0 07 83 c0 03 38 d0 7c 04 84 d2 75 79 48 8d 3d 2e 7a 3f 05 41 8b 74 24 2c <67> 48 0f b9 3a e8 ef b9 21 00 5b 41 5c 5d e9 46 54 66 03 e8 e1 b9 RSP: 0018:ffffc900001bf550 EFLAGS: 00010046 RAX: 0000000000000007 RBX: 0000000000000000 RCX: ffffffffb20c0e90 RDX: 0000000000000000 RSI: 000000000000000a RDI: ffffffffb74b88f0 RBP: ffffc900001bf560 R08: ffff88800197cf00 R09: 0000000000000001 R10: 0000000000000003 R11: 0000000000000003 R12: ffff8880012a6000 R13: 1ffff92000037eae R14: 000000000000000a R15: 0000000000000293 FS: 0000000000000000(0000) GS:ffff8880b49f7000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000555da4a25fa8 CR3: 00000000208e8000 CR4: 00000000000006f0 Call Trace: <TASK> enable_irq+0x121/0x1e0 kernel/irq/manage.c:797 nvme_poll_irqdisable+0x162/0x1c0 drivers/nvme/host/pci.c:1494 nvme_timeout+0x965/0x14b0 drivers/nvme/host/pci.c:1744 blk_mq_rq_timed_out block/blk-mq.c:1653 [inline] blk_mq_handle_expired+0x227/0x2d0 block/blk-mq.c:1721 bt_iter+0x2fc/0x3a0 block/blk-mq-tag.c:292 __sbitmap_for_each_set include/linux/sbitmap.h:269 [inline] sbitmap_for_each_set include/linux/sbitmap.h:290 [inline] bt_for_each block/blk-mq-tag.c:324 [inline] blk_mq_queue_tag_busy_iter+0x969/0x1e80 block/blk-mq-tag.c:536 blk_mq_timeout_work+0x627/0x870 block/blk-mq.c:1763 process_one_work+0x956/0x1aa0 kernel/workqueue.c:3257 process_scheduled_works kernel/workqueue.c:3340 [inline] worker_thread+0x65c/0xe60 kernel/workqueue.c:3421 kthread+0x41a/0x930 kernel/kthread.c:463 ret_from_fork+0x6f8/0x8c0 arch/x86/kernel/process.c:158 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:246 </TASK> irq event stamp: 74478 hardirqs last enabled at (74477): [<ffffffffb5720a9c>] __raw_spin_unlock_irq include/linux/spinlock_api_smp.h:159 [inline] hardirqs last enabled at (74477): [<ffffffffb5720a9c>] _raw_spin_unlock_irq+0x2c/0x60 kernel/locking/spinlock.c:202 hardirqs last disabled at (74478): [<ffffffffb57207b5>] __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:108 [inline] hardirqs last disabled at (74478): [<ffffffffb57207b5>] _raw_spin_lock_irqsave+0x85/0xa0 kernel/locking/spinlock.c:162 softirqs last enabled at (74304): [<ffffffffb1e9466c>] __do_softirq kernel/softirq.c:656 [inline] softirqs last enabled at (74304): [<ffffffffb1e9466c>] invoke_softirq kernel/softirq.c:496 [inline] softirqs last enabled at (74304): [<ffffffffb1e9466c>] __irq_exit_rcu+0xdc/0x120 ---truncated--- | ||||
| CVE-2026-5947 | 1 Isc | 1 Bind | 2026-05-21 | 7.5 High |
| Undefined behavior may result due to a race condition leading to a use-after-free violation. If BIND receives an incoming DNS message signed with SIG(0), it begins work to validate that signature. If, during that validation, the "recursive-clients" limit is reached (as would occur during a query flood), and that same DNS message is discarded per the limit, there is a brief window of time while the SIG(0) validation may attempt to read the now-discarded DNS message. This issue affects BIND 9 versions 9.20.0 through 9.20.22, 9.21.0 through 9.21.21, and 9.20.9-S1 through 9.20.22-S1. BIND 9 versions 9.18.28 through 9.18.49 and 9.18.28-S1 through 9.18.49-S1 are NOT affected. | ||||

| CVE-2026-43430 | 1 Linux | 1 Linux Kernel | 2026-05-20 | 4.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: usb: yurex: fix race in probe The bbu member of the descriptor must be set to the value standing for uninitialized values before the URB whose completion handler sets bbu is submitted. Otherwise there is a window during which probing can overwrite already retrieved data. | ||||
| CVE-2026-23558 | 1 Xen | 1 Xen | 2026-05-19 | 7.8 High |
| The adjustments made for XSA-379 as well as those subsequently becoming XSA-387 still left a race window, when a HVM or PVH guest does a grant table version change from v2 to v1 in parallel with mapping the status page(s) via XENMEM_add_to_physmap. Some of the status pages may then be freed while mappings of them would still be inserted into the guest's secondary (P2M) page tables. | ||||
| CVE-2026-32848 | 1 Netbsd | 1 Src | 2026-05-19 | 4.7 Medium |
| NetBSD prior to commit ec8451e contains a race condition vulnerability in cryptodev_op() within the opencrypto subsystem that allows local attackers to trigger a double-free condition by concurrently issuing CIOCCRYPT operations on the same session identifier on SMP systems. Attackers can exploit mutable per-operation state embedded in the csession struct to corrupt kernel heap memory. | ||||

| CVE-2026-8741 | 1 Emqx | 1 Emqx | 2026-05-18 | 3.1 Low |
| A vulnerability has been found in EMQX up to 6.2.0. This affects an unknown function of the file apps/emqx/src/emqx_persistent_session_ds.erl of the component QoS 2 PUBLISH Packet Handler. Such manipulation leads to race condition. The attack may be performed from remote. A high complexity level is associated with this attack. The exploitability is reported as difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure. | ||||
| CVE-2026-42594 | 2 Gotenberg, Thecodingmachine | 2 Gotenberg, Gotenberg | 2026-05-18 | 7.5 High |
| Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.32.0, the webhook middleware spawns a goroutine that holds a reference to the request's echo.Context after the synchronous handler returns ErrAsyncProcess and Echo recycles the context back to its sync.Pool. When a concurrent request claims the recycled context, c.Reset() clears the store. If the webhook goroutine reaches hardTimeoutMiddleware at that moment, an unchecked type assertion on a nil store entry panics outside any recover() scope, crashing the Gotenberg process. Any anonymous caller reaches the webhook path (default webhook-deny-list filters only the webhook destination, not the submitter). A single-source stress of ~24 webhook requests plus ~60 GET /version requests crashes the process in about two seconds. This vulnerability is fixed in 8.32.0. | ||||

| CVE-2026-43163 | 1 Linux | 1 Linux Kernel | 2026-05-13 | 4.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: md/bitmap: fix GPF in write_page caused by resize race A General Protection Fault occurs in write_page() during array resize: RIP: 0010:write_page+0x22b/0x3c0 [md_mod] This is a use-after-free race between bitmap_daemon_work() and __bitmap_resize(). The daemon iterates over `bitmap->storage.filemap` without locking, while the resize path frees that storage via md_bitmap_file_unmap(). `quiesce()` does not stop the md thread, allowing concurrent access to freed pages. Fix by holding `mddev->bitmap_info.mutex` during the bitmap update. | ||||
