Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986962)

medium Nessus Plugin ID 268956

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-2025-986962 advisory.

In the Linux kernel, the following vulnerability has been resolved:

mISDN: fix possible memory leak in mISDN_register_device()

Afer commit 1fa5ae857bb1 (driver core: get rid of struct device's bus_id string array), the name of device is allocated dynamically, add put_device() to give up the reference, so that the name can be freed in kobject_cleanup() when the refcount is 0.

Set device class before put_device() to avoid null release() function WARN message in device_release().

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.
