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

DCVD (Dual-Channel Cross-Modal Vulnerability Detection) is a unified framework that jointly performs function-level vulnerability detection and statement-level localization. It extracts control-dependency and semantic features via two parallel branches and fuses them using contrastive alignment and bidirectional cross-attention. The model incorporates explicit supervision at both granularities, achieving superior performance on a large real-world vulnerability benchmark compared to state-of-the-art methods.
