On the drm_gem_handle_create() error path it\ncalls drm_gem_object_release() instead of dropping that reference.\n\ndrm_gem_object_release() is the inverse of drm_gem_object_init() and does\nnot touch the reference count or call obj->funcs->free(), so it is only\ncorrect as the last step of a destructor, as in\nvirtio_gpu_cleanup_object(). Using it here leaves the bo at refcount 1\nwith no remaining reference, so virtio_gpu_free_object() never runs and\nthe shmem pages, sg table and virtio_gpu_object are leaked. Since\nvirtio_gpu_object_create() has already set bo->created,\nVIRTIO_GPU_CMD_RESOURCE_UNREF is not queued either, leaking the host-side\nresource and the resource id.\n\ndrm_gem_handle_create_tail() drops the handle reference on all of its\ninternal error paths, so the caller only has to drop its own. Use\ndrm_gem_object_put(), matching the success path below.","state":0,"publishedAt":"2026-10-18T15:19:24.25+00:00","modifiedAt":"2026-10-19T09:22:36.271+00:00","affected":[{"ecosystem":"Vendor
