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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/21dbc9f4d0bdd3b22f91beabc7840064bf11594f","https://git.kernel.org/stable/c/aea934a221ec6a867221e5b765f65f1857befd53","https://git.kernel.org/stable/c/e283009151d3d131447c2edda500199c5fda5f72"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98604","score":0.00198,"percentile":0.0945,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
