Unity Linux 20.1070e Security Update: kernel (UTSA-2025-990121)

medium Nessus Plugin ID 272541

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-2025-990121 advisory.

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

filelock: Fix fcntl/close race recovery compat path

When I wrote commit 3cad1bc01041 (filelock: Remove locks reliably when fcntl/close race is detected), I missed that there are two copies of the code I was patching: The normal version, and the version for 64-bit offsets on 32-bit kernels.
Thanks to Greg KH for stumbling over this while doing the stable backport...

Apply exactly the same fix to the compat path for 32-bit kernels.

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.
