In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix GEM object leak on ENOMEM in userptr ioctl
When amdgpu hmm range alloc() fails amdgpu gem userptr ioctl() returns
-ENOMEM right away and skips the cleanup every other error path goes
through. The GEM object, the bo->parent reference on the VM root and the
MMU notifier registration are all left behind.
Use release object here, not user pages done, range is still NULL at
this point.
(cherry picked from commit bbe739e407a542073ec1a7872b14843566b4919e)
