CVE-2022-37336

Local privilege escalation through improper BIOS validation

Published Aug 11, 2023 · Updated Oct 2, 2024

Improper input validation in Intel NUC 10 Performance BIOS firmware allows local users with high privileges to escalate privileges. Intel identifies the affected locus only as BIOS firmware and has not disclosed which input is mishandled or how validation fails. Exploitation requires local high-privilege access and can alter protected data or interrupt system availability, while Intel reports no confidentiality impact.
