The DxgkDdiEscape handler for 0x5000027 accepts a user provided pointer,
|
||
but does no checks on it before using it.
|
||
|
||
...
|
||
DWORD* user_ptr = escape_5000027_data->user_ptr;
|
||
v32 = user_ptr[2];
|
||
v33 = user_ptr + 3;
|
||
if ( v32 != -1 )
|
||
v33 = (_DWORD *)v32;
|
||
sub_91C24(miniport_context_, *user_ptr, user_ptr[1], v33, (__int64)&escape_data_);
|
||
...
|
||
|
||
The PoC I’ve provided causes a read on said pointer, but based on inspecting where this pointer
|
||
is passed it seems like there is at least 1 code path that can result in a write (I haven't
|
||
confirmed this though).

To reproduce, compile PoC as a x64 executable and run (requires WDK for D3DKMTEscape).
