An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-20637 in the wild and no public exploit code.\n\nAffected product: Mediatek Software Development Kit. 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-2025-20637/ (Markdown: https://insights.sbomify.com/CVE-2025-20637/index.md)","id":"CVE-2025-20637","markdown":"https://insights.sbomify.com/CVE-2025-20637/index.md","name":"CVE-2025-20637","record":{"aliases":["GHSA-qwc4-4mwx-cwrr"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaTek network hardware","requires_auth":"none","summary":"Remote attackers can cause a system hang in MediaTek network hardware via an uncaught exception, resulting in denial of service without user interaction.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"MediaTek","cpe":[{"product":"software_development_kit","vendor":"mediatek"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"},{"id":"CWE-248","name":"Uncaught Exception"}],"description":"In network HW, there is a possible system hang due to an uncaught exception.
