CVE-2026-68364

The CVE-2026-68364 entry concerns the Linux kernel DRM/AMD display subsystem. It describes a deadlock in the ISM path (dc_lock) during suspend caused by amdgpu_dm_ism_disable() waiting for ISM work that itself acquires dc_lock, creating an ABBA deadlock when a worker is in flight at suspend. The ...
