{"id":"CVE-2026-98193","summary":"wifi: libipw: reject TKIP frames without a full MIC","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: libipw: reject TKIP frames without a full MIC\n\nlibipw_michael_mic_verify() assumes that an skb contains an eight-byte\nMichael MIC. 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.","modified":"2026-10-07T02:47:32.091318852Z","published":"2026-10-06T08:44:33.584Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98193.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/06f42accaf3c6aecab1dcc57f68dde6c06c8b380"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9a7fb67364817710c96785ff86b71a2711ee92cb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ac7c08626f67844336086cf563f417566b76f0d7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb7ae8910cc886885aea95abb7c2e578a2341646"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98193.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98193"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b453872c35cfcbdbf5a794737817f7d4e7b1b579"},{"fixed":"9a7fb67364817710c96785ff86b71a2711ee92cb"},{"fixed":"ac7c08626f67844336086cf563f417566b76f0d7"},{"fixed":"bb7ae8910cc886885aea95abb7c2e578a2341646"},{"fixed":"06f42accaf3c6aecab1dcc57f68dde6c06c8b380"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98193.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.14"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98193.json"}}],"schema_version":"1.9.0"}
