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-2026-80274 in the wild and no public exploit code.\n\nAffected product: ISC BIND 9. 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-2026-80274/ (Markdown: https://insights.sbomify.com/CVE-2026-80274/index.md)","id":"CVE-2026-80274","markdown":"https://insights.sbomify.com/CVE-2026-80274/index.md","name":"CVE-2026-80274","record":{"aliases":["ALPINE-CVE-2026-80274","AZL-103335","BELL-CVE-2026-80274","CLSA-2026-1790905625","CLSA-2026-1791226662","DEBIAN-CVE-2026-80274","ECHO-3752-58e5-e69a","GHSA-m66j-g9q7-jxjg","MINI-4888-4xq3-22w6","MINI-4j7g-pwjf-f77q","MINI-mjcw-g4h2-77hq","OESA-2026-4190","UBUNTU-CVE-2026-80274"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"BIND DNS server","requires_auth":"none","summary":"A remote attacker can cause a denial of service in BIND by sending crafted DNSSEC responses that trigger an unexpected program exit.","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-617","name":"Reachable Assertion"}],"description":"If a BIND resolver sends a query for a DNSSEC-signed authoritative zone, and the authoritative server replies with a valid wildcard answer and signed NSEC3 proof, followed by an unsigned NSEC at the same owner name, it will trigger an unexpected program exit.\nThis issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.27-S1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Validating resolver can abort while caching a mismatched NOQNAME proof","id":"CVE-2026-80274","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Comelit 1456B gateway allows low priviledge user to overwrite installer password via unauthorized endpoint","id":"CVE-2026-80275"},"packages":[],"prev":{"headline":"secure cookie attribute bypass with tab","id":"CVE-2026-80255"},"products":["BIND 9"],"published":"2026-09-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-17","vendors":["ISC"]},"summary":"A remote attacker can cause a denial of service in BIND by sending crafted DNSSEC responses that trigger an unexpected program exit.","url":"https://insights.sbomify.com/CVE-2026-80274/"}
