Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-11829 in the wild and no public exploit code.\n\nAffected product: IBM MQ Advanced container images. 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-2026-11829/ (Markdown: https://insights.sbomify.com/CVE-2026-11829/index.md)","id":"CVE-2026-11829","markdown":"https://insights.sbomify.com/CVE-2026-11829/index.md","name":"CVE-2026-11829","record":{"aliases":["GHSA-r558-qrg5-2jq5"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM MQ messaging","requires_auth":"low_privilege","summary":"An authenticated attacker can cause a denial of service in IBM MQ by exploiting improper validation of offset values in MQOPEN requests.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"mq_operator","vendor":"ibm"},{"product":"supplied_mq_advanced_container_images","vendor":"ibm"}],"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-120","name":"Buffer Copy without Checking Size of Input"}],"description":"IBM MQ could allow an authenticated attacker to cause a denial of service due to improper validation of offset values in MQOPEN requests.","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":"IBM MQ Buffer Overflow","id":"CVE-2026-11829","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-11830"},"packages":[],"prev":{"headline":"IBM MQ Buffer Overflow","id":"CVE-2026-11828"},"products":["MQ Advanced container images","MQ Operator"],"published":"2026-10-19","related":[{"cvss_score":8.8,"headline":"IBM MQ Buffer Overflow","id":"CVE-2026-10572","kev_date_added":null,"published":"2026-10-19"},{"cvss_score":8.8,"headline":"IBM MQ Buffer Overflow","id":"CVE-2026-10574","kev_date_added":null,"published":"2026-10-19"},{"cvss_score":8.8,"headline":"IBM MQ Race Condition","id":"CVE-2026-10743","kev_date_added":null,"published":"2026-10-19"},{"cvss_score":8.1,"headline":"IBM MQ Buffer Overflow","id":"CVE-2026-12665","kev_date_added":null,"published":"2026-10-19"},{"cvss_score":8.1,"headline":"IBM MQ Container authentication bypass","id":"CVE-2024-39742","kev_date_added":null,"published":"2024-07-08"},{"cvss_score":7.5,"headline":"IBM MQ Deserialization of Untrusted Data","id":"CVE-2026-12148","kev_date_added":null,"published":"2026-10-19"},{"cvss_score":7.5,"headline":"IBM MQ security bypass","id":"CVE-2024-40681","kev_date_added":null,"published":"2024-09-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-10-19","vendors":["IBM"]},"summary":"An authenticated attacker can cause a denial of service in IBM MQ by exploiting improper validation of offset values in MQOPEN requests.","url":"https://insights.sbomify.com/CVE-2026-11829/"}
