DCVD: Dual-Channel Cross-Modal Fusion for Joint Vulnerability Detection and Localization

ArXi:2605.11015v1 Announce Type: cross Software vulnerability detection plays a critical role in ensuring system security, where real-world auditing requires not only determining whether a function is vulnerable but also pinpointing the specific lines responsible. However, existing approaches either rely on a single information source -- sequential, structural, or semantic -- failing to jointly exploit the complementary strengths across modalities, or treat statement-level localization merely as a byproduct of function-level detection without explicit line-level supervision.
