CVE-2018-14635 is fixed in 15 products on 1 platform, first by neutron-common 2:12.0.3-0ubuntu1, released September 10, 2018. It is not reported as exploited. Patch Radar priority: Routine.
When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3 and 11.0.5 are vulnerable.
