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-2021-34148 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-2021-34148/ (Markdown: https://insights.sbomify.com/CVE-2021-34148/index.md)","id":"CVE-2021-34148","markdown":"https://insights.sbomify.com/CVE-2021-34148/index.md","name":"CVE-2021-34148","record":{"aliases":["DEBIAN-CVE-2021-34148","GHSA-6539-6fh5-h34x","UBUNTU-CVE-2021-34148"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Bluetooth firmware","requires_auth":"none","summary":"Attackers in radio range can crash Cypress WICED BT stack firmware on CYW20735B1 devices by sending crafted LMP packets, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wireless_internet_connectivity_for_embedded_devices","vendor":"cypress"}],"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 in the Cypress WICED BT stack through 2.9.0 for CYW20735B1 devices does not properly handle the reception of LMP_max_slot with a greater ACL Length after completion of the LMP setup procedure, allowing attackers in radio range to trigger a denial of service (firmware crash) 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":true,"headline":"Denial of service in n/a","id":"CVE-2021-34148","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-34149"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-34147"},"products":["n/a"],"published":"2021-09-07","related":[{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2021-34147","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":5.3,"headline":"Denial of service in n/a","id":"CVE-2021-34145","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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers in radio range can crash Cypress WICED BT stack firmware on CYW20735B1 devices by sending crafted LMP packets, causing denial of service.","url":"https://insights.sbomify.com/CVE-2021-34148/"}
