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...

CVE-2026-46263

A flaw was found in the Linux kernel's drm/amd/display component. This vulnerability arises from an out-of-bounds array access when an invalid engid value is used to index the streamencregs array. A local attacker or a privileged process could exploit this memory corruption to potentially execute...

CVE-2026-46263

CVE-2026-46263 is a Linux kernel issue in drm/amd/display where eng_id may index stream_enc_regs beyond its 5-element size, causing out-of-bounds access. The fix adds an explicit bounds check (using ARRAY_SIZE) before indexing stream_enc_regs[eng_id], preventing access when eng_id is ENGINE_ID_DI...
