In the Linux kernel, the following vulnerability has been resolved: power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe of_find_matching_node_and_match() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: power/reset: arm-versatile: Se corrige la pérdida de recuento de referencias en versátil_reboot_probe. 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 ya no lo necesitemos. Se agrega el error of_node_put() faltante para evitar la pérdida de recuento de referencias.
