| Description | In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/userq: fix access to stale wptr mapping Use drm_exec to take both locks i.e vm root bo and wptr_obj bo to access the mapping data properly. This fixes the security issue of unmap the wptr_obj while a queue creation is in progress and passing other bo at same address. (cherry picked from commit 1fc6c8ab45dbee096469c08c13f6099d57a52d6c) |
