Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-000750)

medium Nessus Plugin ID 290862

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-2026-000750 advisory.

The udf_pc_to_char function in fs/udf/symlink.c in the Linux kernel before 3.18.2 relies on component lengths that are unused, which allows local users to cause a denial of service (system crash) via a crafted UDF filesystem image.

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.
