Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-35058 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-2026-35058/ (Markdown: https://insights.sbomify.com/CVE-2026-35058/index.md)","id":"CVE-2026-35058","markdown":"https://insights.sbomify.com/CVE-2026-35058/index.md","name":"CVE-2026-35058","record":{"aliases":["ALPINE-CVE-2026-35058","DEBIAN-CVE-2026-35058","GHSA-22j3-3q48-2rmj","UBUNTU-CVE-2026-35058"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenVPN server","requires_auth":"low_privilege","summary":"Authenticated attackers can cause a denial of service in OpenVPN by sending specially crafted packets that trigger a fatal assertion during key extraction.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenVPN","cpe":[{"product":"openvpn","vendor":"openvpn"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/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-617","name":"Reachable Assertion"}],"description":"Improper validation of packet length during tls-crypt-v2 key extraction in OpenVPN 2.6.0 through 2.6.19 and 2.7_alpha1 through 2.7.1 allows authenticated attackers to trigger a fatal assertion and cause a denial of service via a specially crafted 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":true,"headline":"Denial of service in OpenVPN","id":"CVE-2026-35058","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Anviz Products Missing Authorization","id":"CVE-2026-35061"},"packages":[],"prev":{"headline":"XenForo Stored Cross-Site Scripting via Structured Text Mentions","id":"CVE-2026-35057"},"products":["OpenVPN"],"published":"2026-06-08","related":[{"cvss_score":9.1,"headline":"Memory corruption in OpenVPN","id":"CVE-2025-12106","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":9.1,"headline":"Information disclosure in OpenVPN","id":"CVE-2024-5594","kev_date_added":null,"published":"2025-01-06"},{"cvss_score":9.1,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-7544","kev_date_added":null,"published":"2018-03-16"},{"cvss_score":9,"headline":"Code injection in n/a","id":"CVE-2006-1629","kev_date_added":null,"published":"2006-04-06"},{"cvss_score":8.8,"headline":"Privilege escalation in OpenVPN","id":"CVE-2024-4877","kev_date_added":null,"published":"2025-04-03"},{"cvss_score":7.8,"headline":"Code injection in OpenVPN-GUI","id":"CVE-2021-3606","kev_date_added":null,"published":"2021-07-02"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2018-9336","kev_date_added":null,"published":"2018-05-01"}],"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":"2026-06-08","vendors":["OpenVPN"]},"summary":"Authenticated attackers can cause a denial of service in OpenVPN by sending specially crafted packets that trigger a fatal assertion during key extraction.","url":"https://insights.sbomify.com/CVE-2026-35058/"}
