Repeated WEP entries can\ntherefore overflow the fixed iw_range::encoding_size array returned by\nSIOCGIWRANGE.\n\nReject duplicate cipher suite entries in wiphy_register() instead.\nThis keeps the cipher suite invariant in one place and makes malformed\nwiphy descriptions fail early with -EINVAL, rather than relying on a\nsingle cfg80211 user to handle duplicates correctly.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1305f8b925fe92edf5fec183588dfc7db719180b","https://git.kernel.org/stable/c/4cbb2360f4d8c29e67bc7a8bf6ba0ae096583923","https://git.kernel.org/stable/c/7187d145d9042b037e4f10538f70cf95e380219f","https://git.kernel.org/stable/c/d12e92e72db914e1ea777c6f246f6be75985438e"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-97518","score":0.00157,"percentile":0.04788,"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).
