CVE-2026-80541

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amdgpu: validate GEM_CREATE domain combinations<br /> <br /> AMDGPU_GEM_CREATE checked domain bits against AMDGPU_GEM_DOMAIN_MASK,<br /> but did not validate domain combinations. Userspace could combine<br /> CPU|GTT|VRAM with DOORBELL, GDS, GWS, or OA, making<br /> amdgpu_bo_placement_from_domain() exceed AMDGPU_BO_MAX_PLACEMENTS and<br /> hit BUG_ON().<br /> <br /> Allow combinations only within CPU/GTT/VRAM, and require non-CPU/GTT/<br /> VRAM domains to be specified one at a time. Return -EINVAL for invalid<br /> combinations in amdgpu_gem_create_ioctl().<br /> <br /> v2: Rename helper from amdgpu_gem_domain_valid() to<br /> amdgpu_gem_are_domains_valid() (Christian)<br /> <br /> (cherry picked from commit db39852d0c39843cb02048dfb47e4b8c703e9080)
