Windows KASLR Prefetch Tool

A proof-of-concept tool for bypassing KASLR (kernel ASLR) on Windows 11. Inspired by EntryBleed for Linux.

This tool was developed as part of an exploit targetting Windows 11 24H2. I am not a side-channel expert at all, so this was very much new territory for me and the code is very hacky 😳 Help improving reliability for different CPU types would be much appreciated.

I have done limited testing with the machines at my disposal. I found the techniques I implemented to be quite reliable on modern Intel CPUs, but much less so on AMD.
