Summary		(es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gianfar: ethtool: corrige la fuga de refcount en gfar_get_ts_info La función of_find_compatible_node() devuelve un puntero de nodo con refcount incrementado. Deberíamos usar of_node_put() en ella cuando haya terminado. Agregue el of_node_put() que falta para liberar el recuento.
