  "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.",
