ELM FatFs 漏洞研究 本仓库记录了 FatFs 中六个经确认的安全漏洞，以及一个测试工具套件、模糊测试器和独立的漏洞利用磁盘镜像生成器。 原始 FatFs 源代码可在 FatFs-R0.16 目录中找到。 该项目是对 2017 年一次安全评估的回顾，当时通过手动审计和多日模糊测试在 FatFs 驱动中发现了一些基础但无趣的漏洞。九年后，即 2026 年 3 月，我们使用 Visual Studio Code、GitHub Copilot（自动模式）和一些基本提示重新审视了该项目，没有使用任何特定的循环、工具或技能。结果令人惊讶——在手动审计中忽略的漏洞变得易如反掌，因为 LLM...
