  "details": "In the Linux kernel, the following vulnerability has been resolved:  drm/nouveau/uvmm: fix NULL deref unwinding an OP_MAP_SPARSE op  Each bind_job_op is zeroed by kzalloc_obj() in bind_job_op_from_uop(), and the OP_MAP_SPARSE case in nouveau_uvmm_bind_job_submit() only creates a region, so op-\u003eops stays NULL for a successfully processed sparse map.  If a later op in the same job fails, the reverse unwind loop revisits that op and calls drm_gpuva_ops_free(\u0026uvmm-\u003ebase, op-\u003eops) unconditionally. drm_gpuva_ops_free() dereferences its argument right away (list_for_each_entry_safe on \u0026ops-\u003elist), so a NULL op-\u003eops oopses. The path is reachable by any render-node fd holder, since NOUVEAU_VM_BIND is DRM_RENDER_ALLOW.  Guard the free with IS_ERR_OR_NULL(), as nouveau_uvmm_bind_job_cleanup() already does for the identical free.",
