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-2024-21853 in the wild and no public exploit code.\n\nAffected product: 4th and 5th Generation Intel(R) Xeon(R) Processors. 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-2024-21853/ (Markdown: https://insights.sbomify.com/CVE-2024-21853/index.md)","id":"CVE-2024-21853","markdown":"https://insights.sbomify.com/CVE-2024-21853/index.md","name":"CVE-2024-21853","record":{"aliases":["ALPINE-CVE-2024-21853","BELL-CVE-2024-21853","DEBIAN-CVE-2024-21853","GHSA-f58g-ghv3-pqv3","UBUNTU-CVE-2024-21853"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Intel Xeon Processors","requires_auth":"low_privilege","summary":"An authorized local user can cause a denial of service on Intel Xeon processors due to improper finite state machines in hardware logic.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"intel","cpe":[],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1245","name":"Improper Finite State Machines (FSMs) in Hardware Logic"}],"description":"Improper finite state machines (FSMs) in the hardware logic in some 4th and 5th Generation Intel(R) Xeon(R) Processors may allow an authorized user to potentially enable denial of service via local access.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Denial of service in 4th and 5th Generation Intel(R) Xeon(R) Processors","id":"CVE-2024-21853","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in GoCast","id":"CVE-2024-21855"},"packages":[],"prev":{"headline":"Rapid SCADA Path Traversal","id":"CVE-2024-21852"},"products":["4th and 5th Generation Intel(R) Xeon(R) Processors"],"published":"2024-11-13","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["n/a"]},"summary":"An authorized local user can cause a denial of service on Intel Xeon processors due to improper finite state machines in hardware logic.","url":"https://insights.sbomify.com/CVE-2024-21853/"}
