- Summary
- drm/amdgpu/userq: fix access to stale wptr mapping
- Details
-
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.
