CVE-2024-21960

Local privilege escalation via permissive installation directory

Published May 13, 2025 · Updated Feb 26, 2026

Incorrect permissions in AMD Optimizing CPU Libraries before 4.2.1 allow local users to escalate privileges and execute arbitrary code. The installer assigns overly permissive default access controls to the AOCL installation directory; AMD has not disclosed the affected path, files, or privileged load operation. Exploitation requires local low privileges and user interaction, and successful exploitation executes code with elevated privileges.
