This report synthesises findings from 12 peer-reviewed papers addressing the following research question: What is the cross-domain transferability of vulnerability classification models trained on binary code similarity analysis tasks, as evaluated by accuracy degradation when applied to unseen. 9 claims were extracted from source literature; 8 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.5/10. This report is a machine-generated literature synthesis and does not constitute original research.Research goal: What is the cross-domain transferability of vulnerability classification models trained on binary code similarity analysis tasks, as evaluated by accuracy degradation when applied to unseen programming languages or architectures?Autonomous literature synthesis.
