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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/06f42accaf3c6aecab1dcc57f68dde6c06c8b380","https://git.kernel.org/stable/c/9a7fb67364817710c96785ff86b71a2711ee92cb","https://git.kernel.org/stable/c/ac7c08626f67844336086cf563f417566b76f0d7","https://git.kernel.org/stable/c/bb7ae8910cc886885aea95abb7c2e578a2341646","https://git.kernel.org/stable/c/f448b267968d0ee985e5927c868c8f858169ab34"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98193","score":0.00168,"percentile":0.06049,"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).
