A short TKIP frame makes the unsigned payload length wrap,\ncausing michael_mic() to read past the skb.\n\nCheck that the MIC is present before verifying it, and use the existing\nMICHAEL_MIC_LEN constant for all MIC lengths in the verifier.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98193","source_modified_at":"2026-10-21T12:54:51.640Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"b453872c35cfcbdbf5a794737817f7d4e7b1b579","lessThan":"f448b267968d0ee985e5927c868c8f858169ab34","status":"affected","versionType":"git"},{"version":"b453872c35cfcbdbf5a794737817f7d4e7b1b579","lessThan":"9a7fb67364817710c96785ff86b71a2711ee92cb","status":"affected","versionType":"git"},{"version":"b453872c35cfcbdbf5a794737817f7d4e7b1b579","lessThan":"ac7c08626f67844336086cf563f417566b76f0d7","status":"affected","versionType":"git"},{"version":"b453872c35cfcbdbf5a794737817f7d4e7b1b579","lessThan":"bb7ae8910cc886885aea95abb7c2e578a2341646","status":"affected","versionType":"git"},{"version":"b453872c35cfcbdbf5a794737817f7d4e7b1b579","lessThan":"06f42accaf3c6aecab1dcc57f68dde6c06c8b380","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98193","source_modified_at":"2026-10-21T12:54:51.640Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"2.6.14","status":"affected"},{"version":"0","lessThan":"2.6.14","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.54","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.8","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98193","source_modified_at":"2026-10-21T12:54:51.640Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"9a7fb67364817710c96785ff86b71a2711ee92cb","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98193","source_modified_at":"2026-10-21T12:54:51.640Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"06f42accaf3c6aecab1dcc57f68dde6c06c8b380","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00175,"percentile":0.06677,"score_date":"2026-10-23"},"published_at":"2026-10-06T08:44:33.584Z","modified_at":"2026-10-21T12:54:51.640Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98193","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:54:51.640Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98193","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/f448b267968d0ee985e5927c868c8f858169ab34"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/9a7fb67364817710c96785ff86b71a2711ee92cb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ac7c08626f67844336086cf563f417566b76f0d7"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/bb7ae8910cc886885aea95abb7c2e578a2341646"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/06f42accaf3c6aecab1dcc57f68dde6c06c8b380"}],"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":"2026-10-21T12:54:51.640Z","content_hash":"7576bde53cf833ae8a5bb1aea0983d6cd19aa8db98a66f8e843b8b8bf18299e9"}}
