It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-8916 in the wild and no public exploit code.\n\nAffected product: Google LLC wpantund. 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-2020-8916/ (Markdown: https://insights.sbomify.com/CVE-2020-8916/index.md)","id":"CVE-2020-8916","markdown":"https://insights.sbomify.com/CVE-2020-8916/index.md","name":"CVE-2020-8916","record":{"aliases":["GHSA-9wq6-g8c9-8c8w"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"OpenThread wpantund","requires_auth":"low_privilege","summary":"An attacker can cause a denial of service via memory leak in wpantund when wpanctl interfaces directly with the control driver in debug environments.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Google","cpe":[{"product":"wpantund","vendor":"openthread"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"A memory leak in Openthread's wpantund versions up to commit 0e5d1601febb869f583e944785e5685c6c747be7, when used in an environment where wpanctl is directly interfacing with the control driver (eg: debug environments) can allow an attacker to crash the service (DoS).
