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-2025-11232 in the wild and no public exploit code.\n\nAffected product: ISC Kea. 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-2025-11232/ (Markdown: https://insights.sbomify.com/CVE-2025-11232/index.md)","id":"CVE-2025-11232","markdown":"https://insights.sbomify.com/CVE-2025-11232/index.md","name":"CVE-2025-11232","record":{"aliases":["ALSA-2025:21038","GHSA-wcxf-jmjh-x27q","RHSA-2025:21038","RLSA-2025:21038","openSUSE-SU-2025:15677-1"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Kea DHCP server","requires_auth":"none","summary":"A remote attacker can crash the Kea DHCP server by sending specific option content when DDNS qualifying suffix is configured.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","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-823","name":"Use of Out-of-range Pointer Offset"}],"description":"To trigger the issue, three configuration parameters must have specific settings: \"hostname-char-set\" must be left at the default setting, which is \"[^A-Za-z0-9.-]\"; \"hostname-char-replacement\" must be empty (the default); and \"ddns-qualifying-suffix\" must *NOT* be empty (the default is empty).
