In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix check in amdgpuhmminvalidategfx
For a short moment during alloc/free the userptr BO is not part of his VM, so bo->vmbo can be NULL.
Keep a reference to the VM root PD as parent of the userptr BO so that we can always use that to wait for all submissions of the VM instead of only the one involving the userptr BO.
(cherry picked from commit 631849ff5d603841e74f19f4a5e30fe1f7d7cf30)
