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-2026-002698 advisory.

The vhci_hcd driver in the Linux Kernel before version 4.14.8 and 4.4.114 allows allows local attackers to disclose kernel memory addresses. Successful exploitation requires that a USB device is attached over IP.
