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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

10228 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2022-05-13 01:34 – Updated: 2022-05-13 01:34
VLAI
Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader 9.0.1.5096. 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 Link 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-6434.

Vulnerability from github – Published: 2026-05-27 15:33 – Updated: 2026-05-30 12:30
VLAI
Details

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

bpf: Fix a potential use-after-free of BTF object

Refcounting in the check_pseudo_btf_id() function is incorrect: the __check_pseudo_btf_id() function might get called with a zero refcounted btf. Fix this, and patch related code accordingly.

v3: rephrase a comment (AI) v2: fix a refcount leak introduced in v1 (AI)

Severity
7.8 (High)
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Implementation

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.
