Unity Linux 20.1070a Security Update: kernel (UTSA-2026-005678)

high Nessus Plugin ID 300857

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-2026-005678 advisory.

In the Linux kernel, the following vulnerability has been resolved:

software node: Correct a OOB check in software_node_get_reference_args()

software_node_get_reference_args() wants to get @index-th element, so the property value requires at least '(index + 1) * sizeof(*ref)' bytes but that can not be guaranteed by current OOB check, and may cause OOB for malformed property.

Fix by using as OOB check '((index + 1) * sizeof(*ref) > prop->length)'.

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.
