In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix use-after-free on amdgpu_bo_list mutex

If amdgpu_cs_vm_handling returns r != 0, then it will unlock the bo_list_mutex inside the function amdgpu_cs_vm_handling and again on amdgpu_cs_parser_fini. This problem results in the following use-after-free problem:
