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-2026-000781 advisory.

arch/arm64/mm/dma-mapping.c in the Linux kernel before 4.0.3, as used in the ION subsystem in Android and other products, does not initialize certain data structures, which allows local users to obtain sensitive information from kernel memory by triggering a dma_mmap call.

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
