For connection templates, however, they only log states outside\nthe template state range and still store the value in the connection.\n\nA template can be returned by ordinary connection lookup. TCP and SCTP then\nuse the invalid state as an index into their transition tables.\n\nReject invalid template states in both sync protocol versions before\nlooking up or modifying a connection. The version 1 path handles both\nIPv4 and IPv6 records.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0c61f7d8e18a978aec2a16d9acd5f682f1c72476","https://git.kernel.org/stable/c/1a8f15911352bb3cf4663aa02049c49c7f30e524","https://git.kernel.org/stable/c/50c3f06222eafe9cca7ca51a0ef83311d7cab353","https://git.kernel.org/stable/c/5677e81ffdbfc1c03dcb427fb8b1c38289bed76d","https://git.kernel.org/stable/c/652d9caa5ac925ab012834e325d77b9ed638d4fc"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-97596","score":0.00211,"percentile":0.11185,"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).
