Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-001653)

medium Nessus Plugin ID 290795

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-2026-001653 advisory.

The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.

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.
