An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-81738 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-2026-81738/ (Markdown: https://insights.sbomify.com/CVE-2026-81738/index.md)","id":"CVE-2026-81738","markdown":"https://insights.sbomify.com/CVE-2026-81738/index.md","name":"CVE-2026-81738","record":{"aliases":["GHSA-7xfh-h474-9hf7"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenVPN Windows driver","requires_auth":"none","summary":"Attackers can trigger an out-of-bounds write in the OpenVPN Windows driver via crafted domain search entries, potentially leading to code execution or privilege escalation.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenVPN","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:N/VI:L/VA:L/SC:N/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-193","name":"Off-by-one Error"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"OpenVPN 2.5.0 through 2.7.6 on Windows using the tap-windows6 driver allows attackers to trigger an out-of-bounds write via crafted DOMAIN-SEARCH entries","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":"Memory corruption in OpenVPN","id":"CVE-2026-81738","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Paytm Payment Gateway \u003c 2.8.9 - Unauthenticated Stored XSS via Payment Callback","id":"CVE-2026-81739"},"packages":[],"prev":{"headline":"FAQ Builder AYS 1.6.3 - 1.8.4 - Unauthenticated Stored XSS via ays_get_user_information","id":"CVE-2026-81737"},"products":["OpenVPN"],"published":"2026-09-07","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":"2026-09-08","vendors":["OpenVPN"]},"summary":"Attackers can trigger an out-of-bounds write in the OpenVPN Windows driver via crafted domain search entries, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-81738/"}
