Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-000819)

medium Nessus Plugin ID 283798

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-2026-000819 advisory.

The create_fixed_stream_quirk function in sound/usb/quirks.c in the snd-usb-audio driver in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference or double free, and system crash) via a crafted endpoints value in a USB device descriptor.

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.
