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...

NetworkManager: remote DoS using IPv6 RA with bogus MTU

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...

NetworkManager: denial of service (DoS) attack against IPv6 network stacks due to improper handling of Router Advertisements

A flaw was found in the way NetworkManager handled router advertisements. An unprivileged user on a local network could use IPv6 Neighbor Discovery ICMP to broadcast a non-route with a low hop limit, causing machines to lower the hop limit on existing IPv6 routes. If this limit is small enough,...

DEBIAN-CVE-2015-8215

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 a...

kernel: denial of service (DoS) attack against IPv6 network stacks due to improper handling of Router Advertisements.

It was found that the Linux kernel's TCP/IP protocol suite implementation for IPv6 allowed the Hop Limit value to be set to a smaller value than the default one. An attacker on a local network could use this flaw to prevent systems on that network from sending or receiving network packets...
