Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986752)

high Nessus Plugin ID 268563

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-2025-986752 advisory.

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

netfilter: nf_tables: release flow rule object from commit path

No need to postpone this to the commit release path, since no packets are walking over this object, this is accessed from control plane only.
This helped uncovered UAF triggered by races with the netlink notifier.

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.
