For IPv6 it\nuses sizeof(struct ipv6hdr), while the surrounding IPVS code already\nparsed the packet with ip_vs_fill_iph_skb() and has the real\ntransport-header offset in iph.len.\n\nThis makes TCP state handling look at the wrong bytes when an IPv6\npacket carries extension headers. Use the parsed transport offset passed\ndown from ip_vs_set_state() when reading the TCP header.\n\nFor IPv4 and for IPv6 packets without extension headers, the passed\noffset matches the previous value.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/2500fa3958b1ba51c2b065e39db1b04dfa7e23a2","https://git.kernel.org/stable/c/2d06e0897ce18228d199887f0823b431d841dd03","https://git.kernel.org/stable/c/5848e914b85e360a2dd9d19c00a72e2ea9617dd0","https://git.kernel.org/stable/c/816efb7fc0aeae986e63ac73b428dd97a4ef69f5","https://git.kernel.org/stable/c/c2ee845e292c278fac75bf28d96bc892607fd5c4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80875","score":0.0022,"percentile":0.12517,"date":"2026-11-01"},"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).
