  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/amdgpu: avoid double drm_exec_fini() in userq validate  When new_addition is true, amdgpu_userq_vm_validate() calls drm_exec_fini(\u0026exec) before iterating over the collected HMM ranges and calling amdgpu_ttm_tt_get_user_pages().  If amdgpu_ttm_tt_get_user_pages() fails in that path, the code jumps to unlock_all and calls drm_exec_fini(\u0026exec) a second time on the same exec object. drm_exec_fini() is not idempotent: it frees exec-\u003Eobjects and may also drop exec-\u003Econtended and finalize the ww acquire context.  Route that error path directly to the range cleanup once exec has already been finalized.  Issue found using a prototype static analysis tool and confirmed by code review.  (cherry picked from commit 2802952e4a07306da6ebe813ff1acacc5691851a)",
