medium Nessus Plugin ID 283856

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-2026-001020 advisory.

cipso_v4_validate in include/net/cipso_ipv4.h in the Linux kernel before 3.11.7, when CONFIG_NETLABEL is disabled, allows attackers to cause a denial of service (infinite loop and crash), as demonstrated by icmpsic, a different vulnerability than CVE-2013-0310.

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.
