CVE-2025-0008 · Severity: info · Published 2026-11-10

AMD processors implement Secure Debug Unlock (SDU) to restrict debug access to authorized personnel only. A vulnerability in the authentication verification mechanism allows a local attacker to bypass this protection, potentially gaining unauthorized debug access to the processor and its data. This could enable an attacker to extract sensitive information or further compromise the system.

## Technical details

Insufficient verification of data authenticity in the Secure Debug Unlock mechanism allows a local attacker to bypass authentication controls. The vulnerability requires local access to the system. Exploitation grants unauthorized debug access, potentially enabling privilege escalation, data extraction, or system compromise.
