CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9870 vulnerabilities reference this CWE, most recent first.

GHSA-CM7X-4MVP-C2JF
Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-06 18:31In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Remove cache tags before disabling ATS
The current implementation removes cache tags after disabling ATS, leading to potential memory leaks and kernel crashes. Specifically, CACHE_TAG_DEVTLB type cache tags may still remain in the list even after the domain is freed, causing a use-after-free condition.
This issue really shows up when multiple VFs from different PFs passed through to a single user-space process via vfio-pci. In such cases, the kernel may crash with kernel messages like:

GHSA-CMHX-Q3FP-JHF6
Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-06-28 09:31In the Linux kernel, the following vulnerability has been resolved:
tcp: Add preempt_{disable,enable}_nested() in reqsk_queue_hash_req().
syzbot reported a weird reqsk->rsk_refcnt underflow in __inet_csk_reqsk_queue_drop().
The captured reqsk_put() in __inet_csk_reqsk_queue_drop() is called only when it successfully removes reqsk from ehash.
Moreover, reqsk_timer_handler() calls another reqsk_put() after that.
This indicates that the reqsk was missing both refcnts for ehash and the timer itself.
Since all the syzbot reports had PREEMPT_RT enabled, the only possible scenario is that reqsk_queue_hash_req() is preempted after mod_timer() and before refcount_set(), and then the timer triggered after 1s aborts the reqsk due to its listener's close().
Let's wrap mod_timer() and refcount_set() with preempt_disable_nested() and preempt_enable_nested().
Note that inet_ehash_insert() holds the normal spin_lock() (mutex in PREEMPT_RT), so it must be called outside of preempt_disable_nested(), but this is fine.
The lookup path just ignores 0 sk_refcnt entries in ehash and tries to create another reqsk, but this will fail at inet_ehash_insert().

"details": "In the Linux kernel, the following vulnerability has been resolved:\n\ntcp: Add preempt_{disable,enable}_nested() in reqsk_queue_hash_req().\n\nsyzbot reported a weird reqsk-\u003ersk_refcnt underflow in\n__inet_csk_reqsk_queue_drop().\n\nThe captured reqsk_put() in __inet_csk_reqsk_queue_drop()\nis called only when it successfully removes reqsk from ehash.\n\nMoreover, reqsk_timer_handler() calls another reqsk_put()\nafter that.\n\nThis indicates that the reqsk was missing both refcnts for\nehash and the timer itself.\n\nSince all the syzbot reports had PREEMPT_RT enabled, the only\npossible scenario is that reqsk_queue_hash_req() is preempted\nafter mod_timer() and before refcount_set(), and then the timer\ntriggered after 1s aborts the reqsk due to its listener\u0027s close().\n\nLet\u0027s wrap mod_timer() and refcount_set() with\npreempt_disable_nested() and preempt_enable_nested().\n\nNote that inet_ehash_insert() holds the normal spin_lock()\n(mutex in PREEMPT_RT), so it must be called outside of\npreempt_disable_nested(), but this is fine.\n\nThe lookup path just ignores 0 sk_refcnt entries in ehash\nand tries to create another reqsk, but this will fail at\ninet_ehash_insert().\n\n[0]:\nrefcount_t: underflow; use-after-free.\nWARNING: lib/refcount.c:28 at refcount_warn_saturate+0xb2/0x110 lib/refcount.c:28, CPU#0: ktimers/0/16\nModules linked in:\nCPU: 0 UID: 0 PID: 16 Comm: ktimers/0 Tainted: G L syzkaller #0 PREEMPT_{RT,(full)}\nTainted: [L]=SOFTLOCKUP\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 04/18/2026\nRIP: 0010:refcount_warn_saturate+0xb2/0x110 lib/refcount.c:28\nCode: e4 7d d1 0a 67 48 0f b9 3a eb 4a e8 38 3d 23 fd 48 8d 3d e1 7d d1 0a 67 48 0f b9 3a eb 37 e8 25 3d 23 fd 48 8d 3d de 7d d1 0a \u003c67\u003e 48 0f b9 3a eb 24 e8 12 3d 23 fd 48 8d 3d db 7d d1 0a 67 48 0f\nRSP: 0000:ffffc90000157948 EFLAGS: 00010246\nRAX: ffffffff84a1301b RBX: 0000000000000003 RCX: ffff88801ca98000\nRDX: 0000000000000100 RSI: 0000000000000000 RDI: ffffffff8f72ae00\nRBP: ffffffff99ae3b01 R08: ffff88801ca98000 R09: 0000000000000005\nR10: 0000000000000100 R11: 0000000000000004 R12: ffff8880425ef568\nR13: ffff8880425ef4f8 R14: ffff8880425ef578 R15: 0000000000000000\nFS: 0000000000000000(0000) GS:ffff888126386000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007f7b46710e9c CR3: 000000000dbb6000 CR4: 00000000003526f0\nCall Trace:\n \u003cTASK\u003e\n __refcount_sub_and_test include/linux/refcount.h:400 [inline]\n __refcount_dec_and_test include/linux/refcount.h:432 [inline]\n refcount_dec_and_test include/linux/refcount.h:450 [inline]\n reqsk_put include/net/request_sock.h:136 [inline]\n __inet_csk_reqsk_queue_drop+0x3ce/0x440 net/ipv4/inet_connection_sock.c:1007\n reqsk_timer_handler+0x651/0xdf0 net/ipv4/inet_connection_sock.c:1137\n call_timer_fn+0x192/0x5e0 kernel/time/timer.c:1748\n expire_timers kernel/time/timer.c:1799 [inline]\n __run_timers kernel/time/timer.c:2374 [inline]\n __run_timer_base+0x6a3/0x9f0 kernel/time/timer.c:2386\n run_timer_base kernel/time/timer.c:2395 [inline]\n run_timer_softirq+0x67/0x170 kernel/time/timer.c:2403\n handle_softirqs+0x1de/0x6d0 kernel/softirq.c:622\n __do_softirq kernel/softirq.c:656 [inline]\n run_ktimerd+0x69/0x100 kernel/softirq.c:1151\n smpboot_thread_fn+0x541/0xa50 kernel/smpboot.c:160\n kthread+0x388/0x470 kernel/kthread.c:436\n ret_from_fork+0x514/0xb70 arch/x86/kernel/process.c:158\n ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:245\n \u003c/TASK\u003e",

Mitigation
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
Strategy: Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
