CVE-2022-35276

Local privilege escalation via undisclosed BIOS access control

Published Nov 11, 2022 · Updated Feb 5, 2025

Improper access control in Intel NUC 8 Compute Element BIOS before CBWHL357.0096 allows privileged local users to escalate privileges. Intel has not published the affected BIOS component or the access-control operation that mishandles attacker-controlled input. Exploitation requires high privileges and local access; success crosses a security boundary and compromises confidentiality, integrity, and availability.
