Description
A flaw was found in the Linux kernel's AMD display driver. During Display Power Management Signaling (DPMS) sequences, the driver attempts to access a display sink pointer without verifying whether it is null. A local user could exploit this flaw during display power state transitions, triggering a null pointer dereference that crashes the system and results in a Denial of Service (DoS).
