Description OSIDB Bzimport 2025-12-24 14:07:06 UTC 
In the Linux kernel, the following vulnerability has been resolved:

pinctrl: rockchip: Fix refcount leak in rockchip_pinctrl_parse_groups

of_find_node_by_phandle() returns a node pointer with refcount incremented,
We should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.
