      Disclaimer i dont know if backdoor or stupidity- but code like that do not belong in a driver, that is for sure. I have not spent the required time to do full analysis, but by posting this - someone will do it.

      also- that driver is involved in sending sound over remote desktop. I do not like that there is something custom happening if that file exists when remote desktop connections are happening. I do not currently have the required time to do the investigation- maybe its benign.

      and the drivers looks like it is exploitable anyway - dosdevices can be controlled by per profile devicemappings. And it appears to create a device by \DosDevices\Global\CnxtAudioDevice - Global symlink you can delete with definedosdrive api and create another link.

      but even if exploitable for EOP or for infecting other pcs you connect to MS do not care about PNP drivers being exploitable. They do not write that in rules- and when asked they will say: create full working exploit, do analysis and create a report then we will decide what to do

      I was stupid enough enough to do that - just to waste my time on it being out of scope. Submitted to Lenovo and got a CVE at least. By posting here- I have done my part, would liked to have time for analysing it but I struggle very much with finances so bounty are top priority

      Ohhh- I have explanation now, it is code made to pass the hardware verification tests for the driver to get signed. But- is it allowed to have special case code when tested and still get signed?https://docs.microsoft.com/en-us/windows-hardware/test/hlk/testref/audio-device-testing-prerequisites …

      allright, now knowing this it cuts away 90% of reverse engineering needed. I am downloading an iso with the driver certfication kit- so i can find the test the code is written for. I focussed in on this driver because it gave me BSOD- and that code is a primary suspect
