CVE-2022-0185

CVE-2022-0185 本仓库包含针对 CVE-2022-0185 的演示利用程序。这里有两个版本。 非 kctf 版本（FUSE 版本）专门针对内核版本为 5.11.0-44 的 Ubuntu。它不会直接返回 root shell，而是将 /bin/bash 设置为 suid，从而轻松实现权限提升。调整 singlestart 和 modprobepath 偏移量后，应该能使其适用于大多数内核版本为 5.7 或更高版本的 Ubuntu；对于 5.1 到 5.7 之间的版本，需要像 kctf 版本那样改进 spray 技术。该利用策略依赖于 FUSE 和 SYSVIPC...
