Description

A flaw was found in the Linux kernel's AMD GPU display driver. The `amdgpu_dm_hpd_init()` function, responsible for Hot-Plug Detect (HPD) initialization, may attempt to dereference a null `dc_link` when handling certain connectors. This unconditional dereference can lead to a system crash, allowing a local attacker to cause a Denial of Service (DoS).
