CVE-2024-34163

Local privilege escalation via improper firmware input validation

Published Aug 14, 2024 · Updated Aug 16, 2024

Improper input validation in Intel NUC BIOS firmware allows local privileged users to escalate privileges through unspecified input. Intel has not disclosed the affected firmware component, accepted input, or erroneous validation operation. Exploitation requires local access, high privileges, and additional attack conditions, and the escalation crosses a security boundary.
