Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-006913)

medium Nessus Plugin ID 308292

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-2026-006913 advisory.

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

platform/x86: mxm-wmi: fix memleak in mxm_wmi_call_mx[ds|mx]()

The ACPI buffer memory (out.pointer) returned by wmi_evaluate_method() is not freed after the call, so it leads to memory leak.

The method results in ACPI buffer is not used, so just pass NULL to wmi_evaluate_method() which fixes the memory 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.
