SPOOFING INTERNAL PACKETS FOR MULTIHOMED LINUX DEVICES

Summary from the TLDR InfoSec newsletter

A vulnerability in multihomed Linux devices can be exploited to spoof and inject packets into internal communication streams. This issue can be leveraged by attackers with adjacent network access to manipulate data flows on devices like NAT routers and virtual machines. Mitigations such as anti-spoofing firewall rules and socket binding can help protect against these attacks.
