Unity Linux 20.1070a Security Update: kernel (UTSA-2026-004798)

medium Nessus Plugin ID 291262

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-2026-004798 advisory.

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

 mfd: arizona: Use pm_runtime_resume_and_get() to prevent refcnt leak

 In arizona_clk32k_enable(), we should use pm_runtime_resume_and_get() as pm_runtime_get_sync() will increase the refcnt even when it returns an error.

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.
