Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-000718)

medium Nessus Plugin ID 283752

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-2026-000718 advisory.

The ip6_sk_dst_check function in net/ipv6/ip6_output.c in the Linux kernel before 3.10 allows local users to cause a denial of service (system crash) by using an AF_INET6 socket for a connection to an IPv4 interface.

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.
