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-2026-19446 in the wild and no public exploit code.\n\nAffected product: Ibm Aix. 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-2026-19446/ (Markdown: https://insights.sbomify.com/CVE-2026-19446/index.md)","id":"CVE-2026-19446","markdown":"https://insights.sbomify.com/CVE-2026-19446/index.md","name":"CVE-2026-19446","record":{"aliases":["GHSA-5x8c-w6hj-rjr7"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM AIX OS","requires_auth":"none","summary":"A remote unauthenticated attacker can cause complete system unavailability in IBM AIX and PowerVM VIOS by sending crafted UDP packets to an RPC service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"aix","vendor":"ibm"},{"product":"vios","vendor":"ibm"}],"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-400","name":"Uncontrolled Resource Consumption"}],"description":"IBM AIX 7.2, and 7.3 and IBM PowerVM VIOS 4.1 allows a remote unauthenticated attacker can send a crafted UDP packet to a reachable RPC service, resulting in complete system unavailability and requiring an LPAR restart.","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":"Vulnerabilities in IBM AIX and PowerVM VIOS","id":"CVE-2026-19446","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:aix","products":["ibm:aix","ibm:vios"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Stored XSS in Fileorbis Informatics's FileOrbis","id":"CVE-2026-19447"},"packages":[],"prev":{"headline":"Use-after-free of a server-side SSLContext when sni_callback switches contexts","id":"CVE-2026-19445"},"products":["AIX","PowerVM VIOS"],"published":"2026-08-20","related":[{"cvss_score":10,"headline":"AIX Code Execution","id":"CVE-2025-36250","kev_date_added":null,"published":"2025-11-13"},{"cvss_score":10,"headline":"IBM AIX command execution","id":"CVE-2024-56346","kev_date_added":null,"published":"2025-03-18"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-3187","kev_date_added":null,"published":"2010-08-30"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-3699","kev_date_added":null,"published":"2009-10-15"},{"cvss_score":10,"headline":"Auth bypass in n/a","id":"CVE-2009-3517","kev_date_added":null,"published":"2009-10-01"},{"cvss_score":10,"headline":"Command injection in n/a","id":"CVE-2006-5008","kev_date_added":null,"published":"2006-09-27"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2005-4272","kev_date_added":null,"published":"2005-12-15"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-21","vendors":["IBM"]},"summary":"A remote unauthenticated attacker can cause complete system unavailability in IBM AIX and PowerVM VIOS by sending crafted UDP packets to an RPC service.","url":"https://insights.sbomify.com/CVE-2026-19446/"}
