CVE-2018-14636 describes a vulnerability in OpenStack Neutron versions prior to 13.0.0.0b2, 12.0.3, and 11.0.5, where live-migrated instances can temporarily inspect network traffic of other instances on the same hypervisor. This is due to the instance connecting to the Open vSwitch integration bridge before VLAN filters are applied post-migration, potentially allowing indefinite traffic visibility if the port is administratively down. The vulnerability has a CVSS score of 5.3 (Medium), indicating a network-based attack with high confidentiality impact but high attack complexity, requiring low privileges and no user interaction. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
