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-2026-94084 in the wild and no public exploit code.\n\nAffected product: Oisf Suricata. 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-2026-94084/ (Markdown: https://insights.sbomify.com/CVE-2026-94084/index.md)","id":"CVE-2026-94084","markdown":"https://insights.sbomify.com/CVE-2026-94084/index.md","name":"CVE-2026-94084","record":{"aliases":["DEBIAN-CVE-2026-94084","GHSA-4jpj-5857-48jp","UBUNTU-CVE-2026-94084"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Suricata IDS/IPS","requires_auth":"none","summary":"Suricata suffers from a use-after-free vulnerability in HTTP/2 processing, potentially allowing attackers to execute code or cause denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"suricata","vendor":"oisf"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Suricata before 8.0.7 has an Http2ThreadMultiBuf use-after-free when a transaction is inspected by rules that use http.response_header with and without a transform.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Use after free in Suricata","id":"CVE-2026-94084","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"oisf:suricata","products":["oisf:suricata"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"D-Link DIR-868L Authentication webfa_authentication.cgi strcpy stack-based overflow","id":"CVE-2026-94089"},"packages":[],"prev":{"headline":"Memory corruption in Suricata","id":"CVE-2026-94083"},"products":["Suricata"],"published":"2026-09-20","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-35853","kev_date_added":null,"published":"2023-06-19"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-37592","kev_date_added":null,"published":"2021-11-19"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-10244","kev_date_added":null,"published":"2019-04-04"},{"cvss_score":9.4,"headline":"Memory corruption in Suricata","id":"CVE-2026-94083","kev_date_added":null,"published":"2026-09-20"},{"cvss_score":9.1,"headline":"Suricata http2: protocol-change type confusion can lead to denial of service","id":"CVE-2026-45764","kev_date_added":null,"published":"2026-09-10"},{"cvss_score":8.2,"headline":"Suricata smtp/mime: heap out-of-bounds read quoted-printable decoder","id":"CVE-2026-57228","kev_date_added":null,"published":"2026-09-18"}],"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":"total"},"state":"PUBLISHED","updated":"2026-09-22","vendors":["OISF"]},"summary":"Suricata suffers from a use-after-free vulnerability in HTTP/2 processing, potentially allowing attackers to execute code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-94084/"}
