CVE-2025-68334

Local GPU crash via missing suspend handler

Published Dec 22, 2025 · Updated Dec 22, 2025

Denial of service in the Linux AMD PMC driver on ROG Xbox Ally systems allows local users to crash the AMD GPU during resume. The platform/x86/amd/pmc implementation lacks a Van Gogh SoC handler and therefore fails to complete S0ix suspend on this S3-incapable device. The condition is limited to non-X ROG Xbox Ally hardware and requires a local suspend-and-resume cycle; the resulting impact is a GPU-driver crash rather than data disclosure or modification.
