Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-010858)

medium Nessus Plugin ID 308495

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-2026-010858 advisory.

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

 hfs/hfsplus: avoid WARN_ON() for sanity check, use proper error handling

 Commit 55d1cbbbb29e (hfs/hfsplus: use WARN_ON for sanity check) fixed a build warning by turning a comment into a WARN_ON(), but it turns out that syzbot then complains because it can trigger said warning with a corrupted hfs image.

 The warning actually does warn about a bad situation, but we are much better off just handling it as the error it is. So rather than warn about us doing bad things, stop doing the bad things and return -EIO.

 While at it, also fix a memory leak that was introduced by an earlier fix for a similar syzbot warning situation, and add a check for one case that historically wasn't handled at all (ie neither comment nor subsequent WARN_ON).

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.
