It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-37394 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nova (PyPI): affected all versions; fixed in 23.2.2, 24.1.2, 25.0.2\n- nova (PyPI): affected all versions; fixed in 23.2.2\n- nova (PyPI): affected all versions; fixed in 23.2.2\n- nova (PyPI): affected from 24.0.0; fixed in 24.1.2\n- nova (PyPI): affected from 24.0.0; fixed in 24.1.2\n- nova (PyPI): affected from 25.0.0; fixed in 25.0.2\n- nova (PyPI): affected from 25.0.0; fixed in 25.0.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-37394/ (Markdown: https://insights.sbomify.com/CVE-2022-37394/index.md)","id":"CVE-2022-37394","markdown":"https://insights.sbomify.com/CVE-2022-37394/index.md","name":"CVE-2022-37394","record":{"aliases":["DEBIAN-CVE-2022-37394","GHSA-v725-c588-h936","PYSEC-2026-882","RHSA-2023:1948","UBUNTU-CVE-2022-37394"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"OpenStack Nova","requires_auth":"low_privilege","summary":"An authenticated user can cause compute service failure by manipulating neutron port vnic types, leading to denial of service in SR-IOV deployments.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nova","vendor":"openstack"}],"cvss":{"score":3.3,"severity":"low","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[],"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.
