Exploitation
High exploitation probability; assess promptly
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Linux Kernel是开放源代码的Linux内核系统。 Linux内核网络代码的HASH表实现存在缺陷，远程攻击者可以利用这个漏洞消耗目标机器大量资源，不能对新的包进行路由，导致拒绝服务攻击。 路由缓冲用于缓冲路由通信，以对后续的转发进行判断，当包达到的时候，IP路由代码就会检查通信包并根据路由缓冲进行判断，如果存在缓冲信息，就会重用，否则将产生新路由。Linux内核的网络代码在处理IP头具有相同IPv4源和目的地址，及相同TOS值的包存在缺陷，攻击者精心构建上面描述的包发送给Linux，可导致每个包
