Description OSIDB Bzimport 2025-06-18 12:08:39 UTC 
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.
