(NetworkManager: Denial of Service)

    IPv6 Neighbour Discovery ICMP broadcast containing a non-route with a
      low hop limit causes a Denial of Service by lowering the hop limit on
      existing IPv6 routes in NetworkManager.
  
Impact :

    A remote attacker on the same network segment could cause a Denial of
      Service condition in NetworkManager
  
Workaround :

    There is no known workaround at this time."
