It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-80735 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-80735/ (Markdown: https://insights.sbomify.com/CVE-2026-80735/index.md)","id":"CVE-2026-80735","markdown":"https://insights.sbomify.com/CVE-2026-80735/index.md","name":"CVE-2026-80735","record":{"aliases":["BELL-CVE-2026-80735","DEBIAN-CVE-2026-80735","GHSA-2h35-47m3-h9hp","UBUNTU-CVE-2026-80735"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing check in the Linux kernel OVPN module allows out-of-bounds reads when sockets are shared with other subsystems like BPF SOCKMAP.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\novpn: ensure socket is owned by ovpn before deref sk_user_data\n\nSome subsystems, like BPF SOCKMAP, set sk_user_data without\nactually setting the encap_type.\n\nFor this reason, we must make sure that the type is the\none ovpn expects before dereferencing sk_user_data.\n\nFailing to do so may lead to out-of-bounds reads.","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":"ovpn: ensure socket is owned by ovpn before deref sk_user_data","id":"CVE-2026-80735","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"thunderbolt: Fix bandwidth group reservation indexing","id":"CVE-2026-80736"},"packages":[],"prev":{"headline":"btrfs: initialize inode mapping flags for cached inodes","id":"CVE-2026-80734"},"products":["Linux"],"published":"2026-09-03","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-09-04","vendors":["Linux"]},"summary":"A missing check in the Linux kernel OVPN module allows out-of-bounds reads when sockets are shared with other subsystems like BPF SOCKMAP.","url":"https://insights.sbomify.com/CVE-2026-80735/"}
