Description
A flaw was found in the Linux kernel's drm/amdgpu graphics driver. An unprivileged local attacker with access to /dev/dri/renderD* can trigger an out-of-memory condition during a specific graphics operation, leading to a resource lock not being released. This lock leak causes subsequent operations on the affected graphics context to become unresponsive, resulting in a denial of service that can only be resolved by rebooting the system.
