Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 Linux kernel 4.0之前版本的IPv6栈中的net/ipv6/addrconf.c文件存在安全漏洞，该漏洞源于程序没有检查新的‘MTU’值是否有效。攻击者可借助小于最小值或大于接口MTU（最大传输单元）的值利用该漏洞造成拒绝服务（数据包丢失）。

Source: CVE Program / CVE List V5
Vulnerability Description
net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel before 4.0 does not validate attempted changes to the MTU value, which allows context-dependent attackers to cause a denial of service (packet loss) via a value that is (1) smaller than the minimum compliant value or (2) larger than the MTU of an interface, as demonstrated by a Router Advertisement (RA) message that is not validated by a daemon, a different vulnerability than CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is limited to the NetworkManager product.
