@Tristan @Jeremy, The MAC spoofing aspect of this could based used to DoS or intercept other tenants in a public cloud using shared networks. I'm not familiar with the review process for a patch under embargo, but releasing this could leave public deployments exposed. On the other hand, as I mentioned in the original bug report, this is the IPv4 case of a public IPv6 bug and a fix was first suggested in 2013. Hopefully public deployments have taken additional precautions to harden their environments.
