Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-000998)

high Nessus Plugin ID 283807

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-2026-000998 advisory.

The cipso_v4_validate function in net/ipv4/cipso_ipv4.c in the Linux kernel before 3.4.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an IPOPT_CIPSO IP_OPTIONS setsockopt system call.

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.
