It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-13322 and fix it if it is affected.\n\nWhat it is: CVE-2026-13322 is a low-severity denial of service vulnerability in Red Hat OpenShift Virtualization 4, published on 26 Jun 2026. 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-2026-13322 in the wild and no public exploit code.\n\nAffected product: Red Hat OpenShift Virtualization 4. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-13322/ (Markdown: https://insights.sbomify.com/CVE-2026-13322/index.md)","id":"CVE-2026-13322","markdown":"https://insights.sbomify.com/CVE-2026-13322/index.md","name":"CVE-2026-13322","record":{"aliases":["AZL-91454","GHSA-6f2p-2qg2-qqch","MINI-2fvj-hmpf-r7f4","MINI-5p38-r9qp-8p5h"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"KubeVirt virtualization","requires_auth":"low_privilege","summary":"An attacker with guest access can cause a denial of service in virt-handler by sending unbounded data to the virtio-serial device, leading to memory exhaustion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"kubevirt","vendor":"kubevirt"},{"product":"openshift_virtualization","vendor":"redhat"}],"cvss":{"score":3.8,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"A flaw was found in KubeVirt's downward metrics virtio-serial server.
