I am trying to call MmCopyVirtualMemory but it keeps returning 0x8000000d. just to give some context: The code is running in the right process context and the virtual address is valid. The virtual address in this case basically an address where my DLL is mapped. I am trying to write something to the in memory image using MmCopyVirtualMemory. !vad on the address indicates that it is EXECUTE_WRITECOPY. I was under the impression that if anything is written to a page with EXECUTE_WRITECOPY protection, a private copy of the page will be created for that process. However, I am seeing MmCopyVirtualMemory consistently failing with error 0x8000000d.
And idea what could be going on? Thanks!
