CWE-416
Use After Free
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
CVE-2021-4028 (GCVE-0-2021-4028)
Vulnerability from cvelistv5 – Published: 2022-08-24 00:00 – Updated: 2024-08-03 17:16
VLAI
Summary
A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system.
Severity
No CVSS data available.

Vulnerability from cvelistv5 – Published: 2022-02-04 22:29 – Updated: 2025-04-15 19:10

Summary
A use-after-free vulnerability exists in the JavaScript engine of Foxit Software’s PDF Reader, version 11.1.0.52543. A specially-crafted PDF document can trigger the reuse of previously freed memory, which can lead to arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially-crafted, malicious site if the browser plugin extension is enabled.

Mitigation
Phase: Architecture and Design
Strategy: Language Selection
Description:
- Choose a language that provides automatic memory management.
Mitigation
Phase: Implementation
Strategy: Attack Surface Reduction
Description:
- 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.
No CAPEC attack patterns related to this CWE.
