In the Linux kernel, the following vulnerability has been resolved: net: dsa: mv88e6xxx: Fix refcount leak in mv88e6xxx_mdios_register of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. mv88e6xxx_mdio_register() pass the device node to of_mdiobus_register(). We don't need the device node after it. Add missing of_node_put() to avoid refcount leak.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: dsa: mv88e6xxx: Se corrige la fuga de refcount en mv88e6xxx_mdios_register of_get_child_by_name() devuelve un puntero de nodo con refcount incrementado, deberíamos usar of_node_put() en él cuando haya terminado. mv88e6xxx_mdio_register() pasa el nodo del dispositivo a of_mdiobus_register(). No necesitamos el nodo del dispositivo después de él. Agregue of_node_put() faltante para evitar la fuga de refcount.
