medium Nessus Plugin ID 280514

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-2025-992691 advisory.

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

 rapidio: add check for rio_add_net() in rio_scan_alloc_net()

 The return value of rio_add_net() should be checked. If it fails, put_device() should be called to free the memory and give up the reference initialized in rio_add_net().

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.
