【Bug】it can result windows a crash

[yudhui]

Hello,
I find a bug in the vjoy.sys. when I run the PoC program, the system crashed.

I use windbg to find the position of the bug.

Then, I decompile the vjoy.sys. There's a bug in this code snippet.

[r9+r10] may refer to a fault address. I compare it to the source code in rawpdo.c
In source code:

In binary:

The parm in binary is wrong. I think this results the bug. Maybe there's something wrong when compile the source to binary. You can release your binary correctly and replace it at your website.
