Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-16702 in the wild and no public exploit code.\n\nAffected product: IBM Db2. 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-2026-16702/ (Markdown: https://insights.sbomify.com/CVE-2026-16702/index.md)","id":"CVE-2026-16702","markdown":"https://insights.sbomify.com/CVE-2026-16702/index.md","name":"CVE-2026-16702","record":{"aliases":["GHSA-4hwq-345h-4p3j"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Db2 database","requires_auth":"low_privilege","summary":"A remote authenticated attacker can cause a denial of service in IBM Db2 via a null pointer dereference.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.5 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow a remote authenticated attacker to cause a denial of service due to a null pointer dereference.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Null dereference in Db2","id":"CVE-2026-16702","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-16703"},"packages":[],"prev":{"headline":"IBM i Access Client Solutions (ACS) is Affected By Multiple Vulnerabilities","id":"CVE-2026-16695"},"products":["Db2"],"published":"2026-09-14","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["IBM"]},"summary":"A remote authenticated attacker can cause a denial of service in IBM Db2 via a null pointer dereference.","url":"https://insights.sbomify.com/CVE-2026-16702/"}
