Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix use-after-free race in VM acquire
Replace non-atomic vm->process_info assignment with cmpxchg() to prevent race when parent/child processes sharing a drm_file both try to acquire the same VM after fork().
(cherry picked from commit c7c573275ec20db05be769288a3e3bb2250ec618)
