KMODE_EXCEPTION_NOT_HANDLED Windows 10

[ZirakC]

Using the Dummy2 Driver Source code included within the solution, I added a couple functions taken from Black Bone Driver (COPY_MEM and ProtectMem) It seems like Copy Mem works fine, but whenever I call for ProtectMem I encounter a BSOD "KMODE_EXCEPTION_NOT_HANDLED".

This works fine if I load it through DSEFix on my other driver code (which is a full fledged driver).

I have attached the source with this ticket, wondering if you could help me identify what could be causing this?

This is not TDL issue, debug it by commenting your code line by line. And all your SEH inside driver is not working.

Sorry, last question, you mentioned debug it by commenting my code line by line, would this mean to reboot my PC after each time I load the driver, as it cannot be unloaded on driverless mode?

Thanks,

Yes. Make VM, connect windbg to it, put dbgprint everywhere and trace.
