Unity Linux 20.1070e Security Update: kernel (UTSA-2025-989866)

medium Nessus Plugin ID 273714

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-2025-989866 advisory.

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

netfilter: ipset: Hold module reference while requesting a module

User space may unload ip_set.ko while it is itself requesting a set type backend module, leading to a kernel crash. The race condition may be provoked by inserting an mdelay() right after the nfnl_unlock() call.

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.
