Replace the WARN_ON() and a buggy\nearly exit (which leaves anchor pointing to a freed skb) with real\nerror handling. Wipe the parsing state and tell the reader to retry.\n\nWe already reload the anchor every time we (re)acquire the socket lock,\nso the only condition we need to avoid is an out of bounds read\n(not having enough bytes in the socket for previously parsed record len).\n\nIf some data was read from under TLS but there's enough in the queue\nwe'll reload and decrypt what is most likely not a valid TLS record.\nLeading to some undefined behavior from TLS perspective (corrupting\na stream? missing an alert? missing an attack?) but no kernel crash\nshould take place.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","score":7.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/2fb97ed9e2672b4f6e24ce206ac1a875ce4bcb38","https://git.kernel.org/stable/c/6db015fc4b5d5f63a64a193f65d98da3a7fc811d","https://git.kernel.org/stable/c/db3658a12d5ec4db7185ae7476151a50521b7207","https://git.kernel.org/stable/c/eb0336f213fe88bbdb7d2b19c9c9ec19245a3155","https://git.kernel.org/stable/c/ef50eaab631f9bf519ddbdfa42ccb0528adc1fc8"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:07:46.309729541+00:00"},"epss":{"cve":"CVE-2025-38616","score":0.0021,"percentile":0.11249,"date":"2026-10-31"},"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).
