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-2026-77692 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-2026-77692/ (Markdown: https://insights.sbomify.com/CVE-2026-77692/index.md)","id":"CVE-2026-77692","markdown":"https://insights.sbomify.com/CVE-2026-77692/index.md","name":"CVE-2026-77692","record":{"aliases":["ALPINE-CVE-2026-77692","AZL-103344","BELL-CVE-2026-77692","DEBIAN-CVE-2026-77692","ECHO-1b16-c971-86d1","GHSA-h634-6r6v-4pg6","MINI-2v4r-cwmp-q862","MINI-gggc-r6q2-9mmj","MINI-rmqp-qrpr-mxcv","UBUNTU-CVE-2026-77692"],"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 crash the BIND DNS server by sending a malformed DNS-over-HTTPS request with an invalid signature, requiring DoH to be enabled.","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-476","name":"NULL Pointer Dereference"}],"description":"An attacker can cause `named` to abort by sending a crafted DNS-over-HTTPS request with a cryptographically invalid SIG(0) record, and then closing the transport connection prematurely.\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":"Unauthenticated remote crash of named via a single DoH SIG(0) request","id":"CVE-2026-77692","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":"Order Tip for WooCommerce \u003c 1.6.0 - Shop Manager+ Arbitrary File Deletion via delete_exported_csv_file_ajax","id":"CVE-2026-77693"},"packages":[],"prev":{"headline":"Amelia Pro 9.0 - 9.8 - Unauthenticated Payment Bypass","id":"CVE-2026-77689"},"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 crash the BIND DNS server by sending a malformed DNS-over-HTTPS request with an invalid signature, requiring DoH to be enabled.","url":"https://insights.sbomify.com/CVE-2026-77692/"}
