#LinuxKernel IPv4 #TCP 高危漏洞曝光，AI 利用漏洞可以远程获得 root 权限并执行任意代码。
不过该漏洞利用起来并不容易，A 社研究人员使用 Claude AI 在具有 MPTCP 监听的服务器上成功发起攻击，但 MPTCP 并非默认启用。
当然即便如此用户也需要关注自己使用的 Linux 发行版，及时升级到最新内核修复漏洞。

Linux 7.4's merge window is open: Rust replaces 11,470 lines of C in Binder, AMD HDMI 2.1 goes on by default, and EEVDF cuts latency up to 55%. Not installable yet — -rc1 lands ~Nov 1.

the fix is tiny: kfree() → kfree_rcu() in two places.
readers were already using RCU. the destructor just wasn't waiting for the grace period.
the bug dates back to a lock-free change that's been in kernels since 4.4.

the bug: during a TCP handshake, IPv4 options get handed to the new socket without being copied.
a retransmitted SYN on another CPU can still be reading them when the socket is freed.
classic race → use-after-free in ip_options_build()

🚀 Kernel upgrade successful!
My 2011 iMac is now running Ubuntu 26.04 LTS with the new Linux kernel 7.0.0-42-generic. The upgrade went smoothly, everything works, and YouTube playback in Firefox feels even smoother. 💚🐧
Old hardware, new life!

Your expensive cloud observability stack is frozen, but do not worry, the Linux kernel has been hallucinating a zero-byte dashboard in RAM this whole time. 🫠 Read how to use it before your nodes crash completely. #DevOps #LinuxKernel

A #Linuxkernel bug that gives full root access sat in public code from 2011 until an AI research tool found it this year. Open source means anyone can read the code. It only protects you when someone actually reads it.
