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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9821 vulnerabilities reference this CWE, most recent first.

Details

In SensorManager::assertStateLocked of SensorManager.cpp in Android 7.1.1, 7.1.2, 8.0, 8.1, and 9, there is a possible use after free due to improper locking. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Vulnerability from github – Published: 2025-05-09 09:33 – Updated: 2025-11-12 21:31
VLAI
Details

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

drm/xe: Use local fence in error path of xe_migrate_clear

The intent of the error path in xe_migrate_clear is to wait on locally generated fence and then return. The code is waiting on m->fence which could be the local fence but this is only stable under the job mutex leading to a possible UAF. Fix code to wait on local fence.

(cherry picked from commit 762b7e95362170b3e13a8704f38d5e47eca4ba74)

GHSA-5C2V-7JGP-GFHR

Vulnerability from github – Published: 2024-07-12 15:31 – Updated: 2025-11-04 00:30
VLAI
Details

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

net: bridge: mst: fix suspicious rcu usage in br_mst_set_state

I converted br_mst_set_state to RCU to avoid a vlan use-after-free but forgot to change the vlan group dereference helper. Switch to vlan group RCU deref helper to fix the suspicious rcu usage warning.

Severity
7.8 (High)

GHSA-5C32-VRPQ-FGR5

Vulnerability from github – Published: 2023-08-16 21:31 – Updated: 2025-06-03 03:30
VLAI
Details

A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a kernel information leak problem.

Severity
6.6 (Medium)

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.
