CVE-2019-10638利用情况
暂无补丁情况
官方补丁披露时间
2019-07-06漏洞描述
在5.1.7之前的Linux kernel中，攻击者可以使用内核为无连接协议（例如UDP和ICMP）生成的IP ID值来跟踪设备。当此类流量发送到多个目标IP地址时，有可能获得（计数器数组索引的）哈希冲突，从而（通过枚举）获得哈希密钥。可以通过托管使用WebRTC或gQUIC的精心制作的网页来强制UDP流量到达攻击者控制的IP地址，从而进行攻击。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接：https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.1.7
