Unity Linux 20.1050e Security Update: kernel (UTSA-2026-102026)

medium Nessus Plugin ID 338515

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-2026-102026 advisory.

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

ipmi: Check event message buffer response for bad data

The event message buffer response data size got checked later when processing, but check it right after the response comes back. It appears some BMCs may return an empty message instead of an error when fetching events.

There are apparently some new BMCs that make this error, so we need to compensate.

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.
