Neutron

Incorrect RBAC policy in OpenStack Neutron before 28.0.1 allows an authenticated project manager to set device_owner on ports of shared networks they do not own to privileged network-service values (e.g., 'network:dhcp'), obtaining trusted network-service port behavior without owning the underlying network. Depending on backend and deployment configuration, this enables DHCP, MAC, or IP spoofing against co-tenants sharing that network, effectively bypassing anti-spoofing and security group protections. This is a confirmed regression of CVE-2015-5240 (OSSA-2015-018); no public exploit or active exploitation (CISA KEV) has been identified at time of analysis.
