This is a proof-of-concept research project, illustrating how to synthesize hardware machine check exceptions for processor exploitation and privilege escalation.
The described issue is not yet fully mitigated; a complete toolset will be released in the near future, including:
- Machine check synthesis kernel module
- MCA bank exploration utilities
- Northbridge MCE fuzzer
- End-to-end exploitation toolset
- Exploit payload
Stay tuned.
