{"id":"CVE-2026-98185","summary":"wifi: mwifiex: validate scan response extents","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mwifiex: validate scan response extents\n\nmwifiex_ret_802_11_scan() subtracts the fixed response fields and the\nfirmware-provided BSS length from resp-\u003esize without first proving that\neither extent fits. A short response or oversized BSS length can\ntherefore underflow tlv_buf_size and make the TLV parser walk beyond the\ncommand response.\n\nCompute the fixed extent from the selected normal or background scan\nresponse. Validate that the fixed fields and BSS data fit before deriving\nthe TLV extent and entering the parser.","modified":"2026-10-08T02:52:52.747079561Z","published":"2026-10-06T08:44:27.654Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98185.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/25217c5f6ce0bf3004f80c129464cd35fe9a420f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3687d7d48070838cc2953431b3a27717cab0aaf6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/48312f0085aa1577d6d41af2a079b34de17c1a57"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7106ad8b74f50cca1ef36131f327d2c78f556daa"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9cff2f39ed38a32070b08364c4c9346e85b8f9ec"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c4943323fda22ef27bb6479b9d328ae48c63f64c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cb0008480ed7d5cf76f3ad9668a91bbb7d0b4417"},{"type":"WEB","url":"https://git.kernel.org/stable/c/dccf5ecaad4d8d43c545921f20328e8f91af8698"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98185.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98185"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5e6e3a92b9a4c9416b17f468fa5c7fa2233b8b4e"},{"fixed":"25217c5f6ce0bf3004f80c129464cd35fe9a420f"},{"fixed":"48312f0085aa1577d6d41af2a079b34de17c1a57"},{"fixed":"dccf5ecaad4d8d43c545921f20328e8f91af8698"},{"fixed":"c4943323fda22ef27bb6479b9d328ae48c63f64c"},{"fixed":"cb0008480ed7d5cf76f3ad9668a91bbb7d0b4417"},{"fixed":"9cff2f39ed38a32070b08364c4c9346e85b8f9ec"},{"fixed":"7106ad8b74f50cca1ef36131f327d2c78f556daa"},{"fixed":"3687d7d48070838cc2953431b3a27717cab0aaf6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98185.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"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-2026-98185.json"}}],"schema_version":"1.9.0"}
