Unity Linux 20.1050e Security Update: kernel (UTSA-2026-007503)

medium Nessus Plugin ID 307127

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-2026-007503 advisory.

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

mips: cavium-octeon: Fix missing of_node_put() in octeon2_usb_clocks_start

We should call of_node_put() for the reference 'uctl_node' returned by of_get_parent() which will increase the refcount. Otherwise, there will be a refcount leak bug.

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.
