CVE-2022-38099

Local privileged-user escalation

Published Nov 11, 2022 · Updated Feb 5, 2025

Improper input validation in Intel NUC 11 Compute Element BIOS firmware before EBTGL357.0065 allows local users to escalate privileges. Intel has not disclosed the affected BIOS routine, the untrusted input, or the unsafe operation performed after validation fails. Exploitation requires high privileges and local access; success crosses a security boundary and grants control over protected confidentiality, integrity, and availability.
