cve-2021-4034-mock

CVE-2021-4034 PwnKit 模拟漏洞系统 该项目是一个模拟系统，用于重现 Linux pkexec 守护进程中发现的 CVE-2021-4034（越界读/写） 漏洞的核心运行原理。在没有实际 SUID 权限提升的情况下，在受控环境中安全地模拟了环境变量内存区域越界及恶意载荷注入机制。 特别是，该模拟系统能够检测最新 Linux 内核的 execve 防御机制（传递空数组时强制插入空字符串从而形成 argc=1 的现象），并通过修正偏移量，成功模拟了过去存在漏洞的内存环境。 📂 文件结构 root@kitploit: cve-2021-4034-mock/ ├──...
