CVE-2025-24308

Local privilege escalation via improper UEFI error-handler validation

Published May 13, 2025 · Updated Feb 26, 2026

Improper input validation in Intel Server D50DNP and M50FCP UEFI before R01.02.0003 allows local users to escalate privileges. The firmware error handler accepts insufficiently validated input, but Intel has not disclosed the affected field, operation, or execution path. Reachability requires privileged local access; Intel has not described the higher privilege obtained or the concrete data, code, or availability consequences.
