Abstract

The advent of Large Language Models (LLMs) has enabled advancement in automated code generation, translation, and summarization. Despite their promise, evaluating the use of LLMs in repairing real-world code vulnerabilities remains underexplored. In this study, we address this gap by evaluating the capability of advanced LLMs, such as ChatGPT-4 and Claude, in fixing memory corruption vulnerabilities in real-world C/C++ code. We meticulously curated 223 real-world C/C++ code snippets encompassing a spectrum of memory corruption vulnerabilities, ranging from straightforward memory leaks to intricate buffer errors. Our findings demonstrate the proficiency of LLMs in rectifying simple memory errors like leaks, where fixes are confined to localized code segments. However, their effectiveness diminishes when addressing complicated vulnerabilities necessitating reasoning about cross-cutting concerns and deeper program semantics. Furthermore, we explore techniques for augmenting LLM performance by incorporating additional knowledge. Our results shed light on both the strengths and limitations of LLMs in automated program repair on genuine code, underscoring the need for advancements in reasoning abilities for handling complex code repair tasks.
