{"id":"CVE-2026-98828","summary":"wifi: ath9k: reject short WMI command responses","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath9k: reject short WMI command responses\n\nath9k_wmi_rsp_callback() removes the validated WMI header and copies\nthe number of bytes expected by the waiting command into its response\nbuffer. A device response shorter than that expectation can therefore\nbe read beyond the skb payload.\n\nRecord -EMSGSIZE for a short response, complete the waiter, and return\nthe stored status from the command path. This also prevents callers from\nconsuming stale response bytes as a successful reply.","modified":"2026-10-19T02:47:33.421969820Z","published":"2026-10-18T15:49:22.580Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98828.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/03ef61d05aa26022327f971b790f07e6bf6e35d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/93ce8ea70451e800601bc9444aa33043de15d67b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3b0137c855a61371d9cf9993b8bcc33c9798202"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0c21130c1c7791ba73b19a3a9ea767c8cd43745"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98828.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98828"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"fb9987d0f748c983bb795a86f47522313f701a08"},{"fixed":"03ef61d05aa26022327f971b790f07e6bf6e35d6"},{"fixed":"e0c21130c1c7791ba73b19a3a9ea767c8cd43745"},{"fixed":"a3b0137c855a61371d9cf9993b8bcc33c9798202"},{"fixed":"93ce8ea70451e800601bc9444aa33043de15d67b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98828.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.35"},{"fixed":"6.12.113"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98828.json"}}],"schema_version":"1.9.0"}
