Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ARM: bcm: Se corrige la fuga de recuento de referencias en bcm_kona_smc_init. of_find_matching_node() devuelve un puntero de nodo con el recuento de referencias incrementado. Debemos usar of_node_put() cuando ya no sea necesario. Se ha añadido la función of_node_put() que falta para evitar la fuga de recuento de referencias.
