  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/amdgpu: validate doorbell_offset in user queue creation  amdgpu_userq_get_doorbell_index() passes the user-provided doorbell_offset to amdgpu_doorbell_index_on_bar() without bounds checking. An arbitrarily large doorbell_offset can cause the calculated doorbell index to fall outside the allocated doorbell BO, potentially corrupting kernel doorbell space.  Validate that doorbell_offset falls within the doorbell BO before computing the BAR index, using u64 arithmetic to prevent overflow.  (cherry picked from commit de1ef4ffd70e1d15f0bf584fd22b1f28cbd5e2ec)",
