What happened
Collection of programming-language and software-security research with several practical defenses and tooling advances: (1) Divergent Multi-Version Execution (DME) proposes a runtime semantic-consistency verifier for diversified replicas that detects correlated control- and data-pointer faults by comparing canonical instruction traces — a mitigation for silent data corruption, tampering, and fault attacks. (2) OverrideFuzz introduces a two-phase, semantic-aware grammar fuzzer targeting script runtimes (CPython, Lua, QuickJS) that models override hooks/metamethods and reflection to reach script
