Unity Linux 20.1070a Security Update: kernel (UTSA-2025-392013)

high Nessus Plugin ID 267101

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-2025-392013 advisory.

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

 s390/dasd: fix error recovery leading to data corruption on ESE devices

 Extent Space Efficient (ESE) or thin provisioned volumes need to be formatted on demand during usual IO processing.

 The dasd_ese_needs_format function checks for error codes that signal the non existence of a proper track format.

 The check for incorrect length is to imprecise since other error cases leading to transport of insufficient data also have this flag set.
 This might lead to data corruption in certain error cases for example during a storage server warmstart.

 Fix by removing the check for incorrect length and replacing by explicitly checking for invalid track format in transport mode.

 Also remove the check for file protected since this is not a valid ESE handling case.

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.
