Unity Linux 20.1070e Security Update: kernel (UTSA-2026-000501)

medium Nessus Plugin ID 282031

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-2026-000501 advisory.

 A stack information leak flaw was found in s390/s390x in the Linux kernels memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the kernel data.

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.
