It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-17255 in the wild and no public exploit code.\n\nAffected product: Ibm I. 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-2026-17255/ (Markdown: https://insights.sbomify.com/CVE-2026-17255/index.md)","id":"CVE-2026-17255","markdown":"https://insights.sbomify.com/CVE-2026-17255/index.md","name":"CVE-2026-17255","record":{"aliases":["GHSA-v475-h857-w8m4"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM i OS","requires_auth":"none","summary":"Remote attackers can cause a denial of service on IBM i systems by sending malformed ICMPv6 Router Advertisements.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"i","vendor":"ibm"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to improper validation of the prefix length in ICMPv6 Router Advertisements.","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 i is Affected By Denial of Service Vulnerability []","id":"CVE-2026-17255","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:i","products":["ibm:i"],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"IBM i is Affected By Multiple Vulnerabilities in Debug Server","id":"CVE-2026-17259"},"packages":[],"prev":{"headline":"Memory corruption in TL-MR6400 v7.0","id":"CVE-2026-17252"},"products":["i"],"published":"2026-09-04","related":[{"cvss_score":9.9,"headline":"IBM i is Affected By An Improper Control of Code Generation Vulnerability in HTTP Server Administration GUI","id":"CVE-2026-96119","kev_date_added":null,"published":"2026-10-12"},{"cvss_score":9.9,"headline":"IBM i is Affected By Remote Code Execution Vulnerability []","id":"CVE-2026-16860","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.8,"headline":"IBM i is Affected By Multiple Vulnerabilities in the Debug Server","id":"CVE-2026-17083","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.8,"headline":"IBM i is Affected By Remote Code Execution Vulnerability in Line Printer Daemon []","id":"CVE-2026-17218","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":9.6,"headline":"IBM i is Affected By Multiple Vulnerabilities in Navigator for i","id":"CVE-2026-17276","kev_date_added":null,"published":"2026-08-12"},{"cvss_score":8.9,"headline":"IBM i Is Affected By Multiple Vulnerabilities in IBM Java SDK and IBM Java Runtime","id":"CVE-2026-18193","kev_date_added":null,"published":"2026-08-13"},{"cvss_score":8.9,"headline":"IBM i is Affected By Multiple Vulnerabilities in Navigator for i","id":"CVE-2026-18099","kev_date_added":null,"published":"2026-08-12"}],"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":"2026-09-10","vendors":["IBM"]},"summary":"Remote attackers can cause a denial of service on IBM i systems by sending malformed ICMPv6 Router Advertisements.","url":"https://insights.sbomify.com/CVE-2026-17255/"}
