medium Nessus Plugin ID 283778

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-2026-001212 advisory.

In change_port_settings in drivers/usb/serial/io_ti.c in the Linux kernel before 4.11.3, local users could cause a denial of service by division-by-zero in the serial device layer by trying to set very high baud rates.

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.
