CWE-20
Bugzilla:
1283253: CVE-2015-8215 kernel: MTU value is not validated in IPv6 stack causing packet loss
It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system.
