  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdgpu/userq: only accept doorbell BOs as queue doorbell\n\namdgpu_userq_get_doorbell_index() pins any BO passed as doorbell_handle\ninto the doorbell domain. For a regular BO, TTM moves it with\nttm_bo_move_null() and its contents are lost. Since an importer on the\nsame device gets the exporter's GEM object, a client can do this to a\nbuffer another client shared with it.\n\nReject BOs that were not created in the doorbell domain.\n\nv2: drop the error message, use a local abo variable (Christian)\n\n(cherry picked from commit f7497bbc19db4821c62b9d97b31c9086feb2d917)",
