CVE-2026-0101 · Severity: info · Published 2026-11-12

AMD Power Management Firmware (PMFW) fails to properly validate input parameters, allowing a local attacker to crash the system or cause service interruption. This requires local access to the affected device and could impact system availability but poses no risk of data loss or privilege escalation.
