Linux存在一个盲点，暴露用户于一个严重的安全漏洞Linux Has A Blind Spot That Exposes Users To A Nasty Security Flaw
➀ 2019年引入的Io_uring旨在提高Linux上输入和输出操作的效率和灵活性，但也为Linux安全工具创造了关键盲点。
➁ 安全研究人员发现，io_uring操作可以完全规避传统的系统调用监控，导致无法检测的活动。
➂ 一个名为Curing的rootkit被构建来利用这个漏洞，它可以执行命令、读取文件，并与网络交互，而不使用可检测的系统调用。
➀ Io_uring was introduced in 2019 to improve the efficiency and flexibility of input and output operations on Linux, but it also created critical blind spots for Linux security tools.
➁ Security researchers have discovered that io_uring operations can completely evade conventional system call monitoring, leading to undetectable activities.
➂ A rootkit called Curing was built to exploit this vulnerability, which can execute commands, read files, and interact with the network without detectable system calls.
