Does DxgkDdiMiracastIoControl receives data from user mode ? RRS feed

  • Question

  • iThe DxgkDdiMiracastIoControl routine in KMD receives the parameter pInputBuffer that is also used by the User-Mode routine MiracastIoControl. 

    My question is:

    Is pInputBuffer a buffer passed from User Mode ?  

    From the security perspective, do I need to verify the content of this buffer (user input or attacker) or is this buffer is passed from O.S ?
