Description OSIDB Bzimport 2025-02-26 03:01:48 UTC 
In the Linux kernel, the following vulnerability has been resolved:

powerpc/fsl_rio: Fix refcount leak in fsl_rio_setup

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.
