CVE-2022-50035

CVE-2022-50035 affects the Linux kernel DRM AMDGPU path. The issue is a use-after-free in amdgpu_bo_list mutex handling caused by double-unlocking of bo_list_mutex when amdgpu_cs_vm_handling returns non-zero, which can lead to a refcount underflow (as shown in the trace). The vulnerability is dem...
