Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: soc: rockchip: Se ha corregido la pérdida de recuento de referencias en rockchip_grf_init. of_find_matching_node_and_match devuelve un puntero de nodo con el recuento de referencias incrementado. Deberíamos usar of_node_put() en él cuando haya terminado. Se ha añadido el error of_node_put() que falta para evitar la pérdida de recuento de referencias.
