In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix size validation for non-exclusive domains (v4)
Fix amdgpu_bo_validate_size() to check whether the TTM domain manager for the
requested memory exists, else we get a kernel oops when dereferencing "man".
v2: Make the patch standalone, i.e. not dependent on local patches.
v3: Preserve old behaviour and just check that the manager pointer is not
NULL.
v4: Complain if GTT domain requested and it is uninitialized--most likely a
bug.
