The latter is always returning\n0. The comparison with the network header length will always return that\nenough data is available - even when only 1 or 0 bytes are accessible.\n\nInstead of using offsetofend(), use the more common check for the whole\nheader.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","score":8.1},"cwes":[],"references":["https://git.kernel.org/stable/c/38eaed28e250895d56f4b7989bd65479a511c5c3","https://git.kernel.org/stable/c/7d1a877670bc2e901241073f022ca8d1b2f85f1c","https://git.kernel.org/stable/c/80f62893d135f415e7a374dd47b468ec298f7aed","https://git.kernel.org/stable/c/d2b657c9653fcebca828a2ead13f444e0da68817"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72227","score":0.00331,"percentile":0.26344,"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).
