Linux & Android Kernel Vulnerability research and exploitation

• Do not even bother using WSL2 for Kernel dev/research, you will run into many problems quite fast and it's not worth time to try and troubleshoot. Use a virtual machine instead
• Relevant Hypervisors: (VMware, Hyper-V,Xen)
  • VirtualBox seems to not support mitigations like SMEP
  • Vmware
    • Windows/Linux: VMware Workstation Pro (buy )
    • Mac: VMware Fusion
