Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-001824)

medium Nessus Plugin ID 286529

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-2026-001824 advisory.

The chase_port function in drivers/usb/serial/io_ti.c in the Linux kernel before 3.7.4 allows local users to cause a denial of service (NULL pointer dereference and system crash) via an attempted /dev/ttyUSB read or write operation on a disconnected Edgeport USB serial converter.

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.
