Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88964 in the wild and no public exploit code.\n\nAffected product: OpenVPN. 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-2026-88964/ (Markdown: https://insights.sbomify.com/CVE-2026-88964/index.md)","id":"CVE-2026-88964","markdown":"https://insights.sbomify.com/CVE-2026-88964/index.md","name":"CVE-2026-88964","record":{"aliases":["DEBIAN-CVE-2026-88964","GHSA-wm7f-2ghj-7r8c"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenVPN client","requires_auth":"low_privilege","summary":"Remote authenticated servers can cause denial of service or memory disclosure in OpenVPN clients via crafted domain search options exploiting an integer underflow.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenVPN","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An integer underflow in OpenVPN version 2.7_alpha3 through 2.7.7 on Windows and Android allows remote authenticated servers to cause a denial of service or memory disclosure via crafted domain search options","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":"Integer overflow in OpenVPN","id":"CVE-2026-88964","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Azure Monitor access token disclosure via SSRF","id":"CVE-2026-88967"},"packages":[],"prev":{"headline":"Tutor LMS \u003c= 4.0.8 - Authenticated (Subscriber+) Reflected DOM-Based Cross-Site Scripting via 'redirect_url' Parameter","id":"CVE-2026-88963"},"products":["OpenVPN"],"published":"2026-10-13","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-14","vendors":["OpenVPN"]},"summary":"Remote authenticated servers can cause denial of service or memory disclosure in OpenVPN clients via crafted domain search options exploiting an integer underflow.","url":"https://insights.sbomify.com/CVE-2026-88964/"}
