Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987355)

high Nessus Plugin ID 268704

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-2025-987355 advisory.

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

HID: elan: Fix potential double free in elan_input_configured

'input' is a managed resource allocated with devm_input_allocate_device(), so there is no need to call input_free_device() explicitly or there will be a double free.

According to the doc of devm_input_allocate_device():
* Managed input devices do not need to be explicitly unregistered or
* freed as it will be done automatically when owner device unbinds from
* its driver (or binding fails).

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.
