Unity Linux 20.1070e Security Update: kernel (UTSA-2026-002579)

medium Nessus Plugin ID 284958

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-2026-002579 advisory.

The Serial Attached SCSI (SAS) implementation in the Linux kernel through 4.15.9 mishandles a mutex within libsas, which allows local users to cause a denial of service (deadlock) by triggering certain error- handling code.

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.
