Quality-Assured Fuzz Harness Generation via the Four Principles Framework
Ze Sheng, Dmitrijs Trizna, Luigino Camastra +3
Fuzz testing is the dominant technique for finding memory-safety vulnerabilities in C/C++ software, yet its effectiveness hinges on the quality of fuzz harnesses -- the programs th…
FuzzingBrain V2: A Multi-Agent LLM System for Automated Vulnerability Discovery and Reproduction
Ze Sheng, Zhicheng Chen, Qingxiao Xu +2
Software vulnerabilities pose critical security threats, with nearly 50,000 CVEs reported in 2025. While Large Language Models (LLMs) show promise for automated vulnerability detec…
A Systematic Study of LLM-Based Architectures for Automated Patching
Qingxiao Xu, Ze Sheng, Zhicheng Chen +1
Large language models (LLMs) have shown promise for automated patching, but their effectiveness depends strongly on how they are integrated into patching systems. While prior work…
