Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-381767)

high Nessus Plugin ID 267736

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-2025-381767 advisory.

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

rapidio: fix an API misues when rio_add_net() fails

rio_add_net() calls device_register() and fails when device_register() fails. Thus, put_device() should be used rather than kfree(). Add mport->net = NULL; to avoid a use after free issue.

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.
