An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-51563 in the wild and no public exploit code.\n\nAffected product: FreeBSD. 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-2024-51563/ (Markdown: https://insights.sbomify.com/CVE-2024-51563/index.md)","id":"CVE-2024-51563","markdown":"https://insights.sbomify.com/CVE-2024-51563/index.md","name":"CVE-2024-51563","record":{"aliases":["GHSA-xxc6-q6r3-h584"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"FreeBSD bhyve hypervisor","requires_auth":"none","summary":"A time-of-check to time-of-use race condition in the FreeBSD bhyve hypervisor's virtio_vq_recordon function may lead to undefined behavior or security issues.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"The virtio_vq_recordon function is subject to a time-of-check to time-of-use (TOCTOU) race condition.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"bhyve(8) virtio_vq_recordon time-of-check to time-of-use race","id":"CVE-2024-51563","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"bhyve(8) infinite loop in the hda audio driver","id":"CVE-2024-51564"},"packages":[],"prev":{"headline":"bhyve(8) nvme_opc_get_log_page buffer over-read","id":"CVE-2024-51562"},"products":["FreeBSD"],"published":"2024-11-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["FreeBSD"]},"summary":"A time-of-check to time-of-use race condition in the FreeBSD bhyve hypervisor's virtio_vq_recordon function may lead to undefined behavior or security issues.","url":"https://insights.sbomify.com/CVE-2024-51563/"}
