Graph Is the Verifier: Agentic Reinforcement Learning for Interprocedural Vulnerability Detection

Yikun Li, Ting Zhang, Jiakun Liu +9

The paper presents VulAgentRL, an agentic reinforcement learning framework that leverages code property graphs to collect interprocedural evidence and verify its own reasoning for…

TitanCA: Lessons from Orchestrating LLM Agents to Discover 100+ CVEs

Ting Zhang, Yikun Li, Chengran Yang +15

Software vulnerabilities remain one of the most persistent threats to modern digital infrastructure. While static application security testing (SAST) tools have long served as the…

An Execution-Verified Multi-Language Benchmark for Code Semantic Reasoning

Yikun Li, Jinfeng Jiang, Ting Zhang +7

Evaluating whether large language models (LLMs) can recover execution-relevant program structure, rather than only produce code that passes tests, remains an open problem. Existing…

Autoregressive, Yet Revisable: In Decoding Revision for Secure Code Generation

Chengran Yang, Zichao Wei, Heminghao Deng +6

Large Language Model (LLM) based code generation is predominantly formulated as a strictly monotonic process, appending tokens linearly to an immutable prefix. This formulation con…

Semantics-Aligned, Curriculum-Driven, and Reasoning-Enhanced Vulnerability Repair Framework

Chengran Yang, Ting Zhang, Jinfeng Jiang +9

Current learning-based Automated Vulnerability Repair (AVR) approaches, while promising, often fail to generalize effectively in real-world scenarios. Our diagnostic analysis revea…

Beyond Function-Level Analysis: Context-Aware Reasoning for Inter-Procedural Vulnerability Detection

Yikun Li, Ting Zhang, Jieke Shi +10

Recent progress in ML and LLMs has improved vulnerability detection, and recent datasets have reduced label noise and unrelated code changes. However, most existing approaches stil…
