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-2022-24939 in the wild and no public exploit code.\n\nAffected product: silabs.com Ember ZNet. 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-2022-24939/ (Markdown: https://insights.sbomify.com/CVE-2022-24939/index.md)","id":"CVE-2022-24939","markdown":"https://insights.sbomify.com/CVE-2022-24939/index.md","name":"CVE-2022-24939","record":{"aliases":["GHSA-q35w-7696-fc7r"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zigbee networking stack","requires_auth":"low_privilege","summary":"A malformed Zigbee packet with an invalid destination address causes a stack overflow and device reset in the Ember ZNet stack.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Silabs","cpe":[{"product":"gecko_software_development_kit","vendor":"silabs"},{"product":"zigbee_emberznet","vendor":"silabs"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A malformed packet containing an invalid destination address, causes a stack overflow in the Ember ZNet stack.
