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-2026-000371 advisory.

A flaw was found in the Linux kernel in versions before 5.9-rc6. When changing screen size, an out-of- bounds memory write can occur leading to memory corruption or a denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
