CVE-2023-31271

Local authenticated privilege escalation

Published Feb 14, 2024 · Updated Aug 8, 2024

Improper access control in Intel Virtual RAID on CPU software before 8.0.8.1001 allows local users to escalate privileges. Intel has not disclosed the affected component or the access-control operation that mishandles untrusted input. Exploitation requires authenticated local access, high attack complexity, and user interaction, and successful exploitation grants elevated privileges.
