In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: iwlwifi: fix 22000 series SMEM parsing<br /> <br /> If the firmware were to report three LMACs (which doesn&amp;#39;t<br /> exist in hardware) then using "fwrt-&gt;smem_cfg.lmac[2]" is<br /> an overrun of the array. Reject such and use IWL_FW_CHECK<br /> instead of WARN_ON in this function.
