Name of the Vulnerable Software and Affected Versions OpenStack Neutron versions prior to 7.0.4 OpenStack Neutron versions 8.0.0 through 8.1.0

Description The issue allows remote attackers to bypass an intended MAC-spoofing protection mechanism, potentially causing a denial of service or allowing them to intercept network traffic. This can be achieved via a crafted DHCP discovery message or crafted non-IP traffic.

Recommendations For OpenStack Neutron versions prior to 7.0.4, update to version 7.0.4 or later. For OpenStack Neutron versions 8.0.0 through 8.1.0, update to version 8.1.0 or later. As a temporary workaround, consider restricting access to the IPTables firewall to minimize the risk of exploitation.
