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

drm/virtio: corrige una fuga de objeto en virtio_gpu_resource_create_ioctl()

virtio_gpu_resource_create_ioctl() llama a drm_gem_object_release() en la ruta de error de drm_gem_handle_create() en lugar de liberar la referencia que posee, por lo que obj->funcs->free() nunca se ejecuta y el virtio_gpu_object, sus páginas y su tabla sg, el identificador del recurso y el recurso del lado del host quedan sin liberar.

Use drm_gem_object_put() en su lugar.
