Title: Software Vulnerability Detection Using a Lightweight Graph Neural Network

Abstract:
arXiv:2603.29216v1 Announce Type: cross Abstract: Large Language Models (LLMs) have emerged as a popular choice in vulnerability detection studies given their foundational capabilities, open source availability, and variety of models, but have limited scalability due to extensive compute requirements. Using the natural graph relational structure of code, we show that our proposed graph neural network (GNN) based deep learning model VulGNN for vulnerability detection can achieve performance almos
