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-2026-86128 in the wild and no public exploit code.\n\nAffected product: Watchguard Fireware. 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-2026-86128/ (Markdown: https://insights.sbomify.com/CVE-2026-86128/index.md)","id":"CVE-2026-86128","markdown":"https://insights.sbomify.com/CVE-2026-86128/index.md","name":"CVE-2026-86128","record":{"aliases":["GHSA-pch3-5p8f-436q"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Fireware OS","requires_auth":"none","summary":"Remote attackers can cause denial of service on WatchGuard Fireware OS devices by sending crafted IPv6 packets to the NetFlow feature.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WatchGuard","cpe":[{"product":"fireware","vendor":"watchguard"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"A NULL pointer dereference vulnerability in Fireware OS's NetFlow packet-processing feature allows a remote, unauthenticated attacker to cause a denial of service by sending a specially crafted IPv6 packet.","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":"Fireware OS NULL Pointer Dereference in NetFlow IPv6 Traffic Processing Allows Remote Denial of Service","id":"CVE-2026-86128","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"watchguard:fireware","products":["watchguard:fireware"],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Fireware OS Code Injection in BOVPN Over TLS Client Allows Remote Code Execution","id":"CVE-2026-86131"},"packages":[],"prev":{"headline":"AutoAgent Unauthenticated Remote Code Execution via the Sandbox TCP Command Server","id":"CVE-2026-86124"},"products":["Fireware OS"],"published":"2026-09-29","related":[{"cvss_score":9.8,"headline":"WatchGuard Firebox and XTM Appliances Arbitrary Code Execution","id":"CVE-2022-26318","kev_date_added":"2022-03-25","published":"2022-03-04"},{"cvss_score":9.3,"headline":"WatchGuard Firebox Out of Bounds Write","id":"CVE-2025-14733","kev_date_added":"2025-12-19","published":"2025-12-19"},{"cvss_score":9.3,"headline":"WatchGuard Firebox Out-of-Bounds Write","id":"CVE-2025-9242","kev_date_added":"2025-11-12","published":"2025-09-17"},{"cvss_score":8.8,"headline":"WatchGuard Firebox and XTM Privilege Escalation","id":"CVE-2022-23176","kev_date_added":"2022-04-11","published":"2022-02-24"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2022-31789","kev_date_added":null,"published":"2022-09-06"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2013-6021","kev_date_added":null,"published":"2013-10-19"},{"cvss_score":9.2,"headline":"Fireware OS Code Injection in BOVPN Over TLS Client Allows Remote Code Execution","id":"CVE-2026-86131","kev_date_added":null,"published":"2026-09-29"}],"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":"2026-09-30","vendors":["WatchGuard"]},"summary":"Remote attackers can cause denial of service on WatchGuard Fireware OS devices by sending crafted IPv6 packets to the NetFlow feature.","url":"https://insights.sbomify.com/CVE-2026-86128/"}
