Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9816 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2024-09-11 00:30 – Updated: 2024-09-12 15:33
VLAI
Details

In DevmemIntPFNotify of devicemem_server.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.

An exploitable use-after-free vulnerability exists in the JavaScript engine of Foxit Software's PDF Reader, version 9.1.0.5096. A specially crafted PDF document can trigger a previously freed object in memory to be reused. An attacker needs to trick the user to open the malicious file to trigger.

Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-12-04 15:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

block, bfq: fix uaf for bfqq in bfq_exit_icq_bfqq

Commit 64dc8c732f5c ("block, bfq: fix possible uaf for 'bfqq->bic'") will access 'bic->bfqq' in bic_set_bfqq(), however, bfq_exit_icq_bfqq() can free bfqq first, and then call bic_set_bfqq(), which will cause uaf.

Fix the problem by moving bfq_exit_bfqq() behind bic_set_bfqq().

A flaw was found in the fixed buffer registration code for io_uring (io_sqe_buffer_register in io_uring/rsrc.c) in the Linux kernel that allows out-of-bounds access to physical memory beyond the end of the buffer. This flaw enables full local privilege escalation.

Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-11-24 21:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: cfg80211: Fix use after free for wext

Key information in wext.connect is not reset on (re)connect and can hold data from a previous connection.

Reset key data to avoid that drivers or mac80211 incorrectly detect a WEP connection request and access the freed or already reused memory.

Additionally optimize cfg80211_sme_connect() and avoid an useless schedule of conn_work.

Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-06-30 03:37
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/xe/dma-buf: fix UAF with retry loop

Retry doesn't work here, since bo will be freed on error, leading to UAF. However, now that we do the alloc & init before the attach, we can now combine this as one unit and have the init do the alloc for us. This should make the retry safe.

Reported by Sashiko.

v2: Fix up the error unwind (CI)

(cherry picked from commit 479669418253e0f27f8cf5db01a731352ea592e7)

GHSA-MP3G-VPM9-9VQV

Vulnerability from github – Published: 2024-06-26 19:12 – Updated: 2024-06-26 21:56
VLAI
Summary
@fastly/js-compute has a use-after-free in some host call implementations
Details

Impact

The implementation of the following functions were determined to include a use-after-free bug:

  • FetchEvent.client.tlsCipherOpensslName
  • FetchEvent.client.tlsProtocol
  • FetchEvent.client.tlsClientCertificate
  • FetchEvent.client.tlsJA3MD5
  • FetchEvent.client.tlsClientHello
  • CacheEntry.prototype.userMetadata of the fastly:cache subsystem
  • Device.lookup of the fastly:device subsystem

This bug could allow for an unintended data leak if the result of the preceding functions were sent anywhere else, and often results in a Compute service crash causing an HTTP 500 error to be returned. As all requests to Compute are isolated from one another, the only data at risk is data present for a single request.

Patches

This bug has been fixed in version 3.16.0 of the @fastly/js-compute package.

Workarounds

There are no workarounds for this bug, any use of the affected functions introduces the possibility of a data leak or crash in guest code.

Vulnerability from github – Published: 2026-04-24 15:32 – Updated: 2026-06-01 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

ASoC: qcom: q6apm: move component registration to unmanaged version

q6apm component registers dais dynamically from ASoC toplology, which are allocated using device managed version apis. Allocating both component and dynamic dais using managed version could lead to incorrect free ordering, dai will be freed while component still holding references to it.

Fix this issue by moving component to unmanged version so that the dai pointers are only freeded after the component is removed.

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.
