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-2026-76163 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-2026-76163/ (Markdown: https://insights.sbomify.com/CVE-2026-76163/index.md)","id":"CVE-2026-76163","markdown":"https://insights.sbomify.com/CVE-2026-76163/index.md","name":"CVE-2026-76163","record":{"aliases":["ALPINE-CVE-2026-76163","AZL-103350","BELL-CVE-2026-76163","DEBIAN-CVE-2026-76163","ECHO-2b19-d51c-2494","GHSA-p6fx-3c9f-wcc9","MINI-4mjh-9m6j-6hcp","MINI-5h88-5p89-c9j3","MINI-66rx-j5r8-vh9r","UBUNTU-CVE-2026-76163"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"BIND DNS server","requires_auth":"none","summary":"An attacker can cause a denial of service in BIND by sending a TKEY query when the configuration lacks a global options block.","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 BIND is loaded with a \"`named.conf`\" file that contains no global \"`options`\" block, an attacker can send a query of QTYPE TKEY which may cause an assertion failure and subsequent unexpected program exit.\nThis issue affects BIND 9 versions 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 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":"named aborts on a TKEY query when the user configuration has no global options statement","id":"CVE-2026-76163","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":"Authenticated Server-Side Request Forgery in AIL Framework Crawler Allows Access to Internal Network Resources","id":"CVE-2026-76164"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-76161"},"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":"An attacker can cause a denial of service in BIND by sending a TKEY query when the configuration lacks a global options block.","url":"https://insights.sbomify.com/CVE-2026-76163/"}
