It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2022-37394 - Priority: Routine - CVSS: 3.3 (Medium) - EPSS: 0.0031 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Aug 3, 2022 ## Description An issue was discovered in OpenStack Nova before 23.2.2, 24.x before 24.1.2, and 25.x before 25.0.2. 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. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | nova Debian 12.15 (bookworm) |
