Details

In the Linux kernel, the following vulnerability has been resolved:

mtd: partitions: Fix refcount leak in parse_redboot_of

of_get_child_by_name() 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.

Severity ?

5.5 (Medium)
