存在9年的Linux 提权漏洞,CVE-2026-43284

存在9年的Linux 提权漏洞，CVE-2026-43284

Dirty Frag
影响面大：Linux4/5/6/7
稳定复现：Debian13/Linux7内核一次成功
原理：利用 Linux page cache 的“脏写”
启示：
1.破坏了最小化权限原则
2.网络栈为了“zero copy”性能优化，buffer的所有权越来越复杂。这是一个性能和权限的trade-off
也影响docker/k8s/共享主机云厂商反应迅速：
阿里云、redhat、华为云、腾讯云已发通知，
暂时禁用 xfrm-ESP 模块缓解，也提供了热补丁
运维同学抓紧加固

 #网络安全
