DCVD: Dual-Channel Cross-Modal Fusion for Joint Vulnerability Detection and Localization
DCVD performs joint function-level vulnerability detection and statement-level localization by extracting control-dependency and semantic features in parallel branches, fusing them with contrastive alignment and bidirectional cross-attention, and applying explicit supervision at both granularities.
