Demo exploitation of the POP SS vulnerability (CVE-2018-8897), leading to unsigned code execution with kernel privilages.

- KVA Shadowing should be disabled and the relevant security update should be uninstalled.
- This may not work with certain hypervisors (like VMWare), which discard the pending #DB after INT3.
