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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
12489 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-11-23 03:31 – Updated: 2024-11-23 03:31Foxit PDF Reader Annotation Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of Annotation objects. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25173.

GHSA-J5M6-WGMM-M7M9
Vulnerability from github – Published: 2026-04-24 15:32 – Updated: 2026-04-27 15:30In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix fence put before wait in amdgpu_amdkfd_submit_ib
amdgpu_amdkfd_submit_ib() submits a GPU job and gets a fence from amdgpu_ib_schedule(). This fence is used to wait for job completion.
Currently, the code drops the fence reference using dma_fence_put() before calling dma_fence_wait().
If dma_fence_put() releases the last reference, the fence may be freed before dma_fence_wait() is called. This can lead to a use-after-free.
Fix this by waiting on the fence first and releasing the reference only after dma_fence_wait() completes.
Fixes the below: drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c:697 amdgpu_amdkfd_submit_ib() warn: passing freed memory 'f' (line 696)
(cherry picked from commit 8b9e5259adc385b61a6590a13b82ae0ac2bd3482)

GHSA-J5VH-VFG7-3V94
Vulnerability from github – Published: 2024-11-19 18:31 – Updated: 2026-05-12 15:30In the Linux kernel, the following vulnerability has been resolved:
net/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT
In qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumed to be either root or ingress. This assumption is bogus since it's valid to create egress qdiscs with major handle ffff: Budimir Markovic found that for qdiscs like DRR that maintain an active class list, it will cause a UAF with a dangling class pointer.
In 066a3b5b2346, the concern was to avoid iterating over the ingress qdisc since its parent is itself. The proper fix is to stop when parent TC_H_ROOT is reached because the only way to retrieve ingress is when a hierarchy which does not contain a ffff: major handle call into qdisc_lookup with TC_H_MAJ(TC_H_ROOT).
In the scenario where major ffff: is an egress qdisc in any of the tree levels, the updates will also propagate to TC_H_ROOT, which then the iteration must stop.

"details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: stop qdisc_tree_reduce_backlog on TC_H_ROOT\n\nIn qdisc_tree_reduce_backlog, Qdiscs with major handle ffff: are assumed\nto be either root or ingress. This assumption is bogus since it\u0027s valid\nto create egress qdiscs with major handle ffff:\nBudimir Markovic found that for qdiscs like DRR that maintain an active\nclass list, it will cause a UAF with a dangling class pointer.\n\nIn 066a3b5b2346, the concern was to avoid iterating over the ingress\nqdisc since its parent is itself. The proper fix is to stop when parent\nTC_H_ROOT is reached because the only way to retrieve ingress is when a\nhierarchy which does not contain a ffff: major handle call into\nqdisc_lookup with TC_H_MAJ(TC_H_ROOT).\n\nIn the scenario where major ffff: is an egress qdisc in any of the tree\nlevels, the updates will also propagate to TC_H_ROOT, which then the\niteration must stop.\n\n\n net/sched/sch_api.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)",

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.
