CVE-2022-49367
5.5
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: mv88e6xxx: Fix refcount leak in mv88e6xxx_mdios_register
of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done.
mv88e6xxx_mdio_register() pass the device node to of_mdiobus_register(). We don't need the device node after it.
Add missing of_node_put() to avoid refcount leak.
