{"id":"CVE-2026-98350","summary":"wifi: brcmfmac: cyw: pass PMKID to firmware if present","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: brcmfmac: cyw: pass PMKID to firmware if present\n\nZero out auth_status on initialization. Otherwise, garbage will\nleak from the stack to the firmware (when ssid is less than 32 bytes\nand/or when params-\u003epmkid is set). Then, pass the params-\u003epmkid to the\nfirmware (without it, the firmware caches a garbage PMKID on successful\nauthentication and denies a subsequent association request that includes\nthe PMKID).","modified":"2026-10-07T02:47:34.377234192Z","published":"2026-10-06T08:46:38.525Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98350.json"},"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/6fba6233e9ca7718661e53555a3961c58772c21a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2cf589c7d546557ed60c43f2ec014279265dfbf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e2de8d5eb2984416affdd9559e55f37c7f1bbf47"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98350.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98350"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"66f909308a7c05082919ff214a0bbe2a76aa0283"},{"fixed":"c2cf589c7d546557ed60c43f2ec014279265dfbf"},{"fixed":"6fba6233e9ca7718661e53555a3961c58772c21a"},{"fixed":"e2de8d5eb2984416affdd9559e55f37c7f1bbf47"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98350.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"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-2026-98350.json"}}],"schema_version":"1.9.0"}
