Description

A flaw was found in the Linux kernel's drm/imagination driver. A local user with low privileges could trigger a kernel crash by initiating a GPU hard reset. This occurs because the power management functions pm_runtime_force_suspend() and pm_runtime_force_resume() are improperly used, preventing the GPU clocks from being re-enabled. This vulnerability leads to a Denial of Service (DoS) on the affected system.
