CVE-2026-80541

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate GEMCREATE domain combinations AMDGPUGEMCREATE checked domain bits against AMDGPUGEMDOMAINMASK, but did not validate domain combinations. Userspace could combine CPU|GTT|VRAM with DOORBELL, GDS, GWS, or OA,...

CVE-2026-80541

A vulnerability in the Linux kernel's drm/amdgpu driver allows a local, low-privileged user to trigger a kernel BUG_ON() crash by crafting a GEM_CREATE ioctl with an invalid combination of domain flags (e.g., CPU|GTT|VRAM combined with DOORBELL, GDS, GWS, or OA). The root cause is that while indi...
