CVE-2025-52533Network attack vector

Data disclosure and modification via debug access

Published Feb 12, 2026 · Updated Feb 12, 2026

Improper access control in AMD processor on-chip debug interfaces allows privileged attackers to enable debugging and read or alter protected data. AMD has not disclosed the specific access-control check that the interface omits or how crafted requests activate it. Exploitation requires high privileges, high complexity, and a platform-specific precondition; availability loss is not reported.
