Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987282)

medium Nessus Plugin ID 268239

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-2025-987282 advisory.

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

efi: fix NULL-deref in init error path

In cases where runtime services are not supported or have been disabled, the runtime services workqueue will never have been allocated.

Do not try to destroy the workqueue unconditionally in the unlikely event that EFI initialisation fails to avoid dereferencing a NULL pointer.

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.
