Description
A flaw was found in the Linux kernel's AMD GPU (amdgpu) driver. A local user with access to the debugfs interface can trigger an interrupted lock operation during device testing, which prevents the driver from releasing an acquired runtime power management reference. Consequently, the graphics processing unit (GPU) cannot enter power-saving suspend states, leading to increased power consumption and resource exhaustion.
Statement
This vulnerability is rated as Low impact for Red Hat Enterprise Linux because exploitation requires privileged access to the debugfs filesystem and systems equipped with AMD graphics hardware. Under default configurations, debugfs is restricted to administrative users, significantly limiting exposure to unauthenticated or unprivileged actors. Furthermore, triggering the condition requires an interrupted lock acquisition during driver test routines, resulting only in preventing the hardware from entering a low-power suspend state without compromising data confidentiality or system integrity.
