{"schema":"threatline.record/2","record":{"id":"CVE-2026-97518","aliases":[],"summary":"wifi: cfg80211: reject duplicate wiphy cipher suite entries","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: cfg80211: reject duplicate wiphy cipher suite entries\n\nDuplicate entries in wiphy->cipher_suites do not describe any\nadditional capability, but cfg80211 currently accepts them and leaves\nindividual consumers to deal with them.\n\nOne such consumer is the WEXT compatibility code, which appends a WEP\nkey length for each WEP cipher entry it sees. 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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97518","source_modified_at":"2026-10-21T12:53:01.807Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"2ab658f9ce218ae93b3d2db2b3fe68bfefb81196","lessThan":"d12e92e72db914e1ea777c6f246f6be75985438e","status":"affected","versionType":"git"},{"version":"2ab658f9ce218ae93b3d2db2b3fe68bfefb81196","lessThan":"1305f8b925fe92edf5fec183588dfc7db719180b","status":"affected","versionType":"git"},{"version":"2ab658f9ce218ae93b3d2db2b3fe68bfefb81196","lessThan":"4cbb2360f4d8c29e67bc7a8bf6ba0ae096583923","status":"affected","versionType":"git"},{"version":"2ab658f9ce218ae93b3d2db2b3fe68bfefb81196","lessThan":"7187d145d9042b037e4f10538f70cf95e380219f","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97518","source_modified_at":"2026-10-21T12:53:01.807Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"2.6.32","status":"affected"},{"version":"0","lessThan":"2.6.32","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97518","source_modified_at":"2026-10-21T12:53:01.807Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"1305f8b925fe92edf5fec183588dfc7db719180b","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97518","source_modified_at":"2026-10-21T12:53:01.807Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4cbb2360f4d8c29e67bc7a8bf6ba0ae096583923","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97518","source_modified_at":"2026-10-21T12:53:01.807Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"7187d145d9042b037e4f10538f70cf95e380219f","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00156,"percentile":0.04412,"score_date":"2026-10-23"},"published_at":"2026-09-24T16:05:18.072Z","modified_at":"2026-10-21T12:53:01.807Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97518","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:53:01.807Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97518","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/d12e92e72db914e1ea777c6f246f6be75985438e"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/1305f8b925fe92edf5fec183588dfc7db719180b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4cbb2360f4d8c29e67bc7a8bf6ba0ae096583923"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/7187d145d9042b037e4f10538f70cf95e380219f"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:53:01.807Z","content_hash":"62177fafacbcbb124d465c53b67aa676bb2ecf147a0241160a7b7f19aeaa9c1e"}}
