CVE-2026-46245

A flaw was found in the Linux kernel's AMD GPU display driver. The amdgpudmhpdinit function, responsible for Hot-Plug Detect HPD initialization, may attempt to dereference a null dclink when handling certain connectors. This unconditional dereference can lead to a system crash, allowing a local...
