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