What is CVE-2021-38598?

This vulnerability in OpenStack Neutron allows an attacker controlling a compromised server instance to impersonate the hardware addresses of other devices on the network. When using the linuxbridge driver with ebtables-nft on a Netfilter-based platform, malicious actors can send specially crafted packets that enable them to manipulate network traffic. This could lead to Denial of Service attacks or the unauthorized interception of sensitive information aimed at other systems.
