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-2021-31785 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-2021-31785/ (Markdown: https://insights.sbomify.com/CVE-2021-31785/index.md)","id":"CVE-2021-31785","markdown":"https://insights.sbomify.com/CVE-2021-31785/index.md","name":"CVE-2021-31785","record":{"aliases":["GHSA-8235-3268-fjf9"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","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 a deadlock in Actions Bluetooth chipsets via crafted LMP packets, requiring manual restart to restore service.","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-667","name":"Improper Locking"}],"description":"The Bluetooth Classic implementation on Actions ATS2815 and ATS2819 chipsets does not properly handle the reception of multiple LMP_host_connection_req packets, allowing attackers in radio range to trigger a denial of service (deadlock) of the device via crafted LMP packets.
