Please download and run the Intel System Support Utility for Windows. Select *all* data categories and then have it generate a report. Next, have the tool Save the report to a text file (don't try to use the Submit capability; it doesn't work). Finally, using the Drag and drop here or browse files to attach dialog (below the edit box for the body of your response post), upload and attach this text file to the response post.

Your BIOS is out of date. You have v1.05 and the latest is v1.32.

Your graphics driver (which also provides the display audio driver) is the latest that Lenovo has released, but is a rather dated version. There are later versions available on Intel's site that may address this vulnerability, but I am unsure that you want to upgrade. With laptops, the vendor will often modify the graphics driver packages to (also) support specific capabilities of the laptop. It is important to use only drivers made available by the laptop vendor.

What 'vulnerability' are you attempting to address?

Hhmmm, ok. You need an updated Intel HD Graphics driver package in order to get an updated version of the Intel Display Audio driver. As I said, however, Lenovo is not presently making any updated versions of this package available. You could go to a newer package downloaded directly from the Intel site but, as I said, there is the possibility that Lenovo has been customizing the package and you would lose these customizations (and potentially introduce instability) if you replace it. You should contact Lenovo and see if they are indeed customizing the package. If so, then they need to provide a new customized package. If they are not customizing, then you can use the newer packages downloadable from Intel.

If I may offer input here, please follow the recommendations from INTEL-SA-00354:

Intel recommends that users of Intel® Smart Sound Technology update to the latest version provided by the system manufacturer that addresses these issues. Please contact Lenovo for the updated version of manufacturer drivers.
