Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-003368)

medium Nessus Plugin ID 286899

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-2026-003368 advisory.

The cgroup offline implementation in the Linux kernel through 4.8.11 mishandles certain drain operations, which allows local users to cause a denial of service (system hang) by leveraging access to a container environment for executing a crafted application, as demonstrated by trinity.

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.
