Unity Linux 20.1070a Security Update: kernel (UTSA-2026-005779)

medium Nessus Plugin ID 300894

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-2026-005779 advisory.

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

macintosh: fix possible memory leak in macio_add_one_device()

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

macio device is freed in macio_release_dev(), so the kfree() can be removed.

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.
