Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987560)

medium Nessus Plugin ID 270972

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-987560 advisory.

 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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
