Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-010985)

medium Nessus Plugin ID 309019

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-2026-010985 advisory.

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

memory: pl353-smc: Fix refcount leak bug in pl353_smc_probe()

The break of for_each_available_child_of_node() needs a corresponding of_node_put() when the reference 'child' is not used anymore. Here we do not need to call of_node_put() in fail path as '!match' means no break.

While the of_platform_device_create() will created a new reference by 'child' but it has considered the refcounting.

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.
