By creating a neutron port with the direct vnic_type, creating an instance bound to that port, and then changing the vnic_type of the bound port to macvtap, an authenticated user may cause the compute service to fail to restart, resulting in a possible denial of service. Only Nova deployments configured with SR-IOV are affected.","dates":{"published":"2022-08-03T06:43:44.000Z","modified":"2024-08-03T10:29:20.965Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":3.3,"severity":"low","version":"3.1","versionLabel":"v3.1","source":"NVD","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"OSV
