Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987216)

medium Nessus Plugin ID 267939

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-2025-987216 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 Input: aiptek - properly check endpoint type

 Syzbot reported warning in usb_submit_urb() which is caused by wrong endpoint type. There was a check for the number of endpoints, but not for the type of endpoint.

 Fix it by replacing old desc.bNumEndpoints check with usb_find_common_endpoints() helper for finding endpoints

 Fail log:
