CVE-2022-32569

Local privilege escalation via undisclosed buffer flaw

Published Nov 11, 2022 · Updated Feb 5, 2025

Buffer-bounds flaw in Intel NUC M15 Laptop Kit BIOS firmware before BCTGL357.0074 allows local users to escalate privileges. Intel identifies improper buffer restrictions in the BIOS firmware but has not disclosed the affected routine, buffer, or incorrect operation. Exploitation requires existing high privileges and local access; successful exploitation grants higher privileges across a security boundary.
