Unity Linux 20.1070e Security Update: kernel (UTSA-2026-011187)

medium Nessus Plugin ID 308900

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-2026-011187 advisory.

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

 media: cx231xx: set device_caps for 417

 The video_device for the MPEG encoder did not set device_caps.

 Add this, otherwise the video device can't be registered (you get a WARN_ON instead).

 Not seen before since currently 417 support is disabled, but I found this while experimenting with it.

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.
