Unity Linux 20.1050a Security Update: kernel (UTSA-2026-146627)

high Nessus Plugin ID 373086

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-2026-146627 advisory.

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

drm/omap: dsi: Do not copy isr table

To be able to unregister stuff from isrs, the corresponding table was copied. Nobody seems to unregister stuff that way, so it does not help.
But there are stack-allocated objects passed to these isrs giving chances of UAF of these objects if irqs are unregistered while they are handled, so better do not copy that table.

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.
