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-2021-31787 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-2021-31787/ (Markdown: https://insights.sbomify.com/CVE-2021-31787/index.md)","id":"CVE-2021-31787","markdown":"https://insights.sbomify.com/CVE-2021-31787/index.md","name":"CVE-2021-31787","record":{"aliases":["GHSA-r5g9-33j7-96vc"],"analysis":{"component_type":"hardware_firmware","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Bluetooth chipset firmware","requires_auth":"none","summary":"Attackers in radio range can cause device shutdown by flooding Actions ATS2815 Bluetooth chipsets with unsolicited LMP responses.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ats2815_firmware","vendor":"actions-semi"},{"product":"ats2819_firmware","vendor":"actions-semi"},{"product":"ats2819p_firmware","vendor":"actions-semi"},{"product":"ats2819s_firmware","vendor":"actions-semi"},{"product":"ats2819t_firmware","vendor":"actions-semi"}],"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":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"The Bluetooth Classic implementation on Actions ATS2815 chipsets does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service and shutdown of a device by flooding the target device with LMP_features_res packets.","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-2021-31787","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":"In Hardware Sentry KM before 10.0.01 for BMC PATROL, a cleartext password may be discovered after a failure or timeout of a command.","id":"CVE-2021-31791"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-31786"},"products":["n/a"],"published":"2021-11-30","related":[{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2021-31785","kev_date_added":null,"published":"2021-09-07"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2021-31786","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"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 cause device shutdown by flooding Actions ATS2815 Bluetooth chipsets with unsolicited LMP responses.","url":"https://insights.sbomify.com/CVE-2021-31787/"}
