暂无补丁情况
官方补丁披露时间
2018-09-07漏洞描述
3.9+版的Linux内核容易受到拒绝服务攻击，因为针对IP片段重组的特殊修改数据包的传输率较低。攻击者可能通过发送特制IP片段来导致拒绝服务条件。这些年来，已经发现并修复了IP碎片中的各种漏洞。随着IP片段重组队列大小的增加，当前漏洞（CVE-2018-5391）在Linux内核中变得可利用。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://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git/commit/?id=c30f1fc041b74ecdb072dd44f858750414b8b19f
