Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-011180)

medium Nessus Plugin ID 308994

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-2026-011180 advisory.

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

ASoC: audio-graph-card: fix refcount leak of cpu_ep in __graph_for_each_link()

The of_get_next_child() returns a node with refcount incremented, and decrements the refcount of prev. So in the error path of the while loop, of_node_put() needs be called for cpu_ep.

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.
