Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-001788)

medium Nessus Plugin ID 286396

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-2026-001788 advisory.

The override_release function in kernel/sys.c in the Linux kernel before 3.4.16 allows local users to obtain sensitive information from kernel stack memory via a uname system call in conjunction with a UNAME26 personality.

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.
