Reference:
http://en.wikipedia.org/wiki/Win32_Thread_Information_Block

Code:
FS:[0x124]    

Pointer to KTHREAD (ETHREAD) structure

which is the biggest structure I've ever seen:
http://www.nirsoft.net/kernel_struct/vista/KTHREAD.html

Look at this field:
PVOID KernelStack;

What does make you think ?

Maybe with some tweaks we may end up injecting some code into ring0. Rolling Eyes

What do you think ?
