En el kernel de Linux se ha resuelto la siguiente vulnerabilidad:

drm/virtio: corrige fugas de objetos en virtio_gpu_resource_create_blob_ioctl()

virtio_gpu_resource_create_blob_ioctl() llama a drm_gem_object_release() tanto en la ruta de error de virtio_gpu_resource_assign_uuid() como en la de drm_gem_handle_create(), en lugar de liberar la referencia que le pertenece, por lo que obj->funcs->free() nunca se ejecuta y el virtio_gpu_object, el identificador del recurso y el recurso del lado del host quedan filtrados.

Usa drm_gem_object_put() en su lugar.
