In the Linux kernel, the following vulnerability has been resolved: mtd: parsers: ofpart: Fix refcount leak in bcm4908_partitions_fw_offset of_find_node_by_path() 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: mtd: parsers: ofpart: Se corrige la fuga de recuento de referencias en bcm4908_partitions_fw_offset. of_find_node_by_path() 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.
