Reva: Real-Time Vulnerability Detection through Contextual Probing of Large Language Models
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- REVA detects code vulnerabilities in one second per function by reading LLM internal representations with a trained probe, matching slower agentic detectors' accuracy.
- Why it matters
- Matters for engineers building CI/CD pipelines or code review systems that need real-time vulnerability screening as coding agents generate functions rapidly.
- Watch out
- REVA's 60% accuracy on PrimeVul test set leaves 40% of vulnerabilities undetected; effectiveness on other codebases and vulnerability types remains unclear.
