Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992565)

medium Nessus Plugin ID 280200

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-2025-992565 advisory.

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

 HID: pidff: Fix null pointer dereference in pidff_find_fields

 This function triggered a null pointer dereference if used to search for a report that isn't implemented on the device. This happened both for optional and required reports alike.

 The same logic was applied to pidff_find_special_field and although pidff_init_fields should return an error earlier if one of the required reports is missing, future modifications could change this logic and resurface this possible null pointer dereference again.

 LKML bug report:
 https://lore.kernel.org/all/CAL-gK7f5=R0nrrQdPtaZZr1fd-cdAMbDMuZ_NLA8vM0SX+nGSw@mail.gmail.com

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.
