Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989677)

medium Nessus Plugin ID 274057

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-2025-989677 advisory.

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

cipso: Fix data-races around sysctl.

While reading cipso sysctl variables, they can be changed concurrently.
So, we need to add READ_ONCE() to avoid data-races.

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.
