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.

NetworkManager: remote DoS using IPv6 RA with bogus MTU
GNOME NetworkManager allows remote attackers to cause a denial of service (IPv6 traffic disruption) via a crafted MTU value in an IPv6 Router Advertisement (RA) message, a different vulnerability than CVE-2015-8215.
It was discovered that NetworkManager would set device MTUs based on MTU values received in IPv6 RAs (Router Advertisements), without sanity checking the MTU value first. A remote attacker could exploit this flaw to create a denial of service attack, by sending a specially crafted IPv6 RA packet to disturb IPv6 communication.

CVE-2015-8215 [MEDIUM] CVE-2015-8215 kernel: MTU value is not validated in IPv6 stack causing packet loss
CVE-2015-8215 kernel: MTU value is not validated in IPv6 stack causing packet loss
A vulnerability in net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel before 4.0, where the MTU value was not validated, was found. This allowed context-dependent attackers to cause a denial of service (packet loss) via a value that is either smaller than the minimum compliant value or larger than the MTU of an interface.
