Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986813)

medium Nessus Plugin ID 268628

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-2025-986813 advisory.

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

s390/dasd: add missing discipline function

Fix crash with illegal operation exception in dasd_device_tasklet.
Commit b72949328869 (s390/dasd: Prepare for additional path event handling) renamed the verify_path function for ECKD but not for FBA and DIAG.
This leads to a panic when the path verification function is called for a FBA or DIAG device.

Fix by defining a wrapper function for dasd_generic_verify_path().

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.
