{"schema":"threatline.record/2","record":{"id":"CVE-2026-98604","aliases":[],"summary":"ovpn: replace bind when learning local endpoint","details":"In the Linux kernel, the following vulnerability has been resolved:\n\novpn: replace bind when learning local endpoint\n\nstruct ovpn_bind is published through peer->bind with RCU, but local\nendpoint learning updates bind->local in place under peer->lock. UDP TX\nreads the field without that lock. In particular, a concurrent IPv6\nupdate can therefore result in a torn address read.\n\nUse ovpn_peer_reset_sockaddr to publish a replacement bind when learning\na new local endpoint, just as a remote endpoint change does. Preserve\nthe current remote address and reset the dst cache only after the new\nbind has been published successfully.\n\nTrack remote endpoint changes separately so that float notification and\ntransport-address rehashing remain limited to actual peer floats.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98604","source_modified_at":"2026-10-19T09:22:31.480Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"f0281c1d3732d1ec084fa1e06d1767d33e1a570e","lessThan":"21dbc9f4d0bdd3b22f91beabc7840064bf11594f","status":"affected","versionType":"git"},{"version":"f0281c1d3732d1ec084fa1e06d1767d33e1a570e","lessThan":"e283009151d3d131447c2edda500199c5fda5f72","status":"affected","versionType":"git"},{"version":"f0281c1d3732d1ec084fa1e06d1767d33e1a570e","lessThan":"aea934a221ec6a867221e5b765f65f1857befd53","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98604","source_modified_at":"2026-10-19T09:22:31.480Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.16","status":"affected"},{"version":"0","lessThan":"6.16","status":"unaffected","versionType":"semver"},{"version":"6.18.55","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98604","source_modified_at":"2026-10-19T09:22:31.480Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"21dbc9f4d0bdd3b22f91beabc7840064bf11594f","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00198,"percentile":0.09046,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:19:17.227Z","modified_at":"2026-10-19T09:22:31.480Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98604","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:22:31.480Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98604","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/21dbc9f4d0bdd3b22f91beabc7840064bf11594f"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e283009151d3d131447c2edda500199c5fda5f72"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/aea934a221ec6a867221e5b765f65f1857befd53"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:22:31.480Z","content_hash":"0a388cbf5aeb9e05748eb749cabefe2a85cf66f1ec4cd2eced0a19fccfdfe200"}}
