In the Linux kernel, the following vulnerability has been resolved: soc: qcom: ocmem: Fix refcount leak in of_get_ocmem of_parse_phandle() 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. of_node_put() will check NULL pointer.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: soc: qcom: ocmem: Se corrige la fuga de recuento de referencias en of_get_ocmem. of_parse_phandle() 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. of_node_put() comprobará el puntero NULL.
