An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-10822 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-2026-10822/ (Markdown: https://insights.sbomify.com/CVE-2026-10822/index.md)","id":"CVE-2026-10822","markdown":"https://insights.sbomify.com/CVE-2026-10822/index.md","name":"CVE-2026-10822","record":{"aliases":["ALPINE-CVE-2026-10822","AZL-93114","BELL-CVE-2026-10822","DEBIAN-CVE-2026-10822","ECHO-6303-1fdb-ed48","GHSA-42qr-f5rc-vfw9","MINI-886g-4p46-5c2q","MINI-8h64-fr2m-7wcp","MINI-h926-v2jv-2868","UBUNTU-CVE-2026-10822"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS server software","requires_auth":"none","summary":"An attacker can cause a denial of service in BIND by submitting a malformed DNS key record with an invalid PRIVATEDNS algorithm length.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"},{"id":"CWE-1284","name":"Improper Validation of Specified Quantity in Input"}],"description":"If BIND encounters a particular invalid data structure in a DNS record, it will accept the invalid data, and may subsequently abort and exit.\n\nBIND will first need to store a DNS record for a key (KEY, DNSKEY, etc.).
