CVE-2022-49965

Local denial of service via missing cleanup callbacks

Published Jun 18, 2025 · Updated May 11, 2026

Memory leakage in Linux kernel 5.19 AMDGPU SMU13 power management allows local users to reduce availability through device teardown paths. The SMU v13.0.0 and v13.0.7 power-play tables omit cleanup callbacks, leaving resources allocated when the power-management context is finalized. The affected paths require corresponding AMD SMU13 ASICs, and the published record identifies no specific user-controlled trigger.
