Common Weakness Enumeration

CWE-416

Allowed

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9841 vulnerabilities reference this CWE, most recent first.

GHSA-QH76-9567-4H37

Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-11-25 18:32
VLAI
Details

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

drm/meson: remove drm bridges at aggregate driver unbind time

drm bridges added by meson_encoder_hdmi_init and meson_encoder_cvbs_init were not manually removed at module unload time, which caused dangling references to freed memory to remain linked in the global bridge_list.

When loading the driver modules back in, the same functions would again call drm_bridge_add, and when traversing the global bridge_list, would end up peeking into freed memory.

Once again KASAN revealed the problem:

GHSA-QHP7-446P-XQ88

Vulnerability from github – Published: 2023-11-09 21:30 – Updated: 2024-06-25 21:31
VLAI
Details

A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation.
