CVE-2025-29944

System crash via Sensor Fusion Hub buffer overflow

Published May 15, 2026 · Updated May 15, 2026

Buffer overflow in AMD's Sensor Fusion Hub Driver for affected Ryzen and Athlon processors allows local users to crash the system. The driver writes beyond a destination buffer's bounds, but AMD has not disclosed the responsible routine or attacker-controlled input. Low-privileged local access is required; the documented consequence is availability loss through a system crash, with no reported confidentiality or integrity impact.
