Randomizing the KUSER_SHARED_DATA Structure on Windows

Windows 10 made a lot of improvements in Kernel Address Space Layout Randomization KASLR that increases the cost of exploitation, particularly for remote code execution exploits. Many kernel virtual address space VAS locations including kernel stacks, pools, system PTEs etc. are randomized. A...
