CVE-2022-50155

Estado: AnalizadaMedia (5.5)—

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.
