Unity Linux 20.1070a Security Update: kernel (UTSA-2025-430123)

high Nessus Plugin ID 267604

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-2025-430123 advisory.

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

 Input: synaptics-rmi4 - fix use after free in rmi_unregister_function()

 The put_device() calls rmi_release_function() which frees fn so the dereference on the next line fn->num_of_irqs is a use after free.
 Move the put_device() to the end to fix this.

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.
