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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

11164 vulnerabilities reference this CWE, most recent first.

GHSA-6X9M-MW8M-FQ7F

Vulnerability from github – Published: 2025-08-16 12:30 – Updated: 2025-11-18 18:32
VLAI
Details

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

net: airoha: fix potential use-after-free in airoha_npu_get()

np->name was being used after calling of_node_put(np), which releases the node and can lead to a use-after-free bug. Previously, of_node_put(np) was called unconditionally after of_find_device_by_node(np), which could result in a use-after-free if pdev is NULL.

This patch moves of_node_put(np) after the error check to ensure the node is only released after both the error and success cases are handled appropriately, preventing potential resource issues.

GHSA-6XGC-8M9R-QVGM

Vulnerability from github – Published: 2026-04-01 03:31 – Updated: 2026-04-01 03:31
VLAI
Details

The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state. When a script modifies the zoom property and then triggers a page change, the original view object may be destroyed while stale pointers are still kept and later dereferenced, which under crafted JavaScript and document structures can lead to a use-after-free condition and potentially allow arbitrary code execution.

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.
