When turning to Claude AI to help in sorting through the issue, patches were devised that can deliver up to a "literally yield a 50-80x improvement on the io_uring side for idle systems." The code is on its way to the Linux kernel... 🔗 Source: https://www.phoronix.com/news/AI-50-80x-IO-uring #linux#kernel

Remote authentication bypass in telnetd 远程认证绕过漏洞影响 telnetd 服务 大多数用户可能早已停止运行可通过网络访问的 telnet 服务。但对于仍在使用的用户，Simon Josefsson 发布的安全公告值得关注。 该漏洞存在于 telnetd 服务器中。服务器在调用 `/usr/bin/login`（通常以 root 权限运行）时，会将从客户端接收到的 `USER` 环境变量的值作为最后一个参数传递。 如果客户端精心构造 `USER` 环境变量的值为字符串 `-f root`，并通过 telnet 客户端的 `-a` 或 `--login` 参数将此环境变量发送到服务器，那么客户端将能够绕过正常的身份验证过程，自动以 root 身份登录。 原文链接：https://lwn.net/Articles/1055213/ #安全#漏洞#telnet#Linux #AIGC Read more
