Description OSIDB Bzimport 2025-02-26 03:02:59 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: bgmac: Fix refcount leak in bcma_mdio_mii_register

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.
