medium Nessus Plugin ID 286353

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-2026-003549 advisory.

The swiotlb_print_info function in lib/swiotlb.c in the Linux kernel through 4.14.14 allows local users to obtain sensitive address information by reading dmesg data from a software IO TLB printk 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

Update the affected kernel package.
