I have 3 Surface 2 Laptops that have the Intel Smart Sound Vulnerability. (Intel-SA-00354) Meaning the file IntcAudioBus.sys is on version 9.21.0.3755. I have tried to get the Intel Smart Sound drivers updated and if I use the latest drivers it kills the sound. I keep getting referred to Microsoft from Intel; however, I can't get any help of find anything on the Microsoft website/Forums on this issue. Any help would be appreciated.

    Hi Josh Eades,

    Microsoft is aware of the Intel Management Engine vulnerability (Intel-SA-00354). The Intel vulnerability detection tool currently lists Microsoft Surface devices as vulnerable to this security advisory. Microsoft has investigated the issue and found the following:

    • Remote exploit of this vulnerability requires Intel Active Management Technology (AMT). Current Surface devices do not allow remote connectivity to the ME because our devices do not run AMT.
    • Local exploit of this vulnerability requires Direct Connect Interface (DCI) access via USB, which is not provided on Surface devices.

    Because of this, we believe exploits using this vulnerability are significantly reduced on Surface devices. We care deeply about ensuring our devices are reliable and secure and are working with Intel to generate fixes for current devices, which we expect to release in the near future.

    Kind regards,

    Lavenia,

    We are currently running 21H2 OS build 19044.2965.

    When I install the latest driver, the realtek audio SST disappears and there is an unknown audio device and there isn't any sound output device. Once I restore the original driver the sound issue is resolved.

    I have downloaded the drivers from the cab file listed on this page. Microsoft Update Catalog I extract the files from the CAB file and install the driver from there. Then for the "UnKnown" device it doesn't find the correct drivers from that cab file.
