Unity Linux 20.1050e Security Update: kernel (UTSA-2026-005090)

medium Nessus Plugin ID 296853

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-2026-005090 advisory.

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

 drm/i915/gem: Fix Virtual Memory mapping boundaries calculation

 Calculating the size of the mapped area as the lesser value between the requested size and the actual size does not consider the partial mapping offset. This can cause page fault access.

 Fix the calculation of the starting and ending addresses, the total size is now deduced from the difference between the end and start addresses.

 Additionally, the calculations have been rewritten in a clearer and more understandable form.

 [Joonas: Add Requires: tag] Requires: 60a2066c5005 (drm/i915/gem: Adjust vma offset for framebuffer mmap offset) (cherry picked from commit 97b6784753da06d9d40232328efc5c5367e53417)

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.
