It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-11604 in the wild and no public exploit code.\n\nAffected product: OpenVPN ovpn-dco-win. 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-2026-11604/ (Markdown: https://insights.sbomify.com/CVE-2026-11604/index.md)","id":"CVE-2026-11604","markdown":"https://insights.sbomify.com/CVE-2026-11604/index.md","name":"CVE-2026-11604","record":{"aliases":["GHSA-f6c5-28vq-94w2"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenVPN Windows driver","requires_auth":"low_privilege","summary":"A remote authenticated peer can trigger a heap-based buffer overflow in the OpenVPN Windows driver, causing kernel memory corruption and a system crash.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenVPN","cpe":[{"product":"ovpn-dco-win","vendor":"openvpn"}],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-131","name":"Incorrect Calculation of Buffer Size"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"An incorrect buffer size calculation in the epoch key generator in OpenVPN ovpn-dco-win version 2.0.0 through 2.8.3 allows a remote authenticated peer to trigger a heap-based buffer overflow and kernel memory corruption via a crafted data packet, resulting in a system crash (denial of service).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in ovpn-dco-win","id":"CVE-2026-11604","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Unnecessary validation of DNSSEC signed records","id":"CVE-2026-11605"},"packages":[],"prev":{"headline":"Product Filter Widget for Elementor \u003c= 1.0.6 - Reflected Cross-Site Scripting via 'args[filterFormArray]' Parameter","id":"CVE-2026-11603"},"products":["ovpn-dco-win"],"published":"2026-06-10","related":[{"cvss_score":5.5,"headline":"Memory corruption in ovpn-dco-win","id":"CVE-2025-50054","kev_date_added":null,"published":"2025-06-20"},{"cvss_score":3.3,"headline":"Null dereference in OpenVPN-GUI","id":"CVE-2024-5198","kev_date_added":null,"published":"2025-01-15"}],"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":"2026-06-11","vendors":["OpenVPN"]},"summary":"A remote authenticated peer can trigger a heap-based buffer overflow in the OpenVPN Windows driver, causing kernel memory corruption and a system crash.","url":"https://insights.sbomify.com/CVE-2026-11604/"}
