Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-993190)

medium Nessus Plugin ID 281139

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-2025-993190 advisory.

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

cxl: Fix refcount leak in cxl_calc_capp_routing

of_get_next_parent() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore.
This function only calls of_node_put() in normal path, missing it in the error path.
Add missing of_node_put() to avoid refcount leak.

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.
