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-2021-31612 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-31612/ (Markdown: https://insights.sbomify.com/CVE-2021-31612/index.md)","id":"CVE-2021-31612","markdown":"https://insights.sbomify.com/CVE-2021-31612/index.md","name":"CVE-2021-31612","record":{"aliases":["GHSA-x3mf-x7jh-9gfw"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Bluetooth Classic firmware","requires_auth":"none","summary":"Attackers in radio range can trigger a deadlock on Zhuhai Jieli AC690X devices by sending oversized LMP packets, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac6901_firmware","vendor":"zh-jieli"},{"product":"ac6902_firmware","vendor":"zh-jieli"},{"product":"ac6903_firmware","vendor":"zh-jieli"},{"product":"ac6904_firmware","vendor":"zh-jieli"},{"product":"ac6905_firmware","vendor":"zh-jieli"},{"product":"ac6907_firmware","vendor":"zh-jieli"},{"product":"ac6908_firmware","vendor":"zh-jieli"},{"product":"ac690n_firmware","vendor":"zh-jieli"},{"product":"ac692n_firmware","vendor":"zh-jieli"},{"product":"ac6997_firmware","vendor":"zh-jieli"},{"product":"ac6998_firmware","vendor":"zh-jieli"},{"product":"ac6999_firmware","vendor":"zh-jieli"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"The Bluetooth Classic implementation on Zhuhai Jieli AC690X devices does not properly handle the reception of an oversized LMP packet greater than 17 bytes during the LMP auto rate procedure, allowing attackers in radio range to trigger a deadlock via a crafted LMP packet.","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":"Denial of service in n/a","id":"CVE-2021-31612","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-31613"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-31611"},"products":["n/a"],"published":"2021-09-07","related":[{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2021-31613","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":5.7,"headline":"Denial of service in n/a","id":"CVE-2021-31611","kev_date_added":null,"published":"2021-09-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers in radio range can trigger a deadlock on Zhuhai Jieli AC690X devices by sending oversized LMP packets, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2021-31612/"}
