In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix 22000 series SMEM parsing
If the firmware were to report three LMACs (which doesn't exist in hardware) then using "fwrt->smemcfg.lmac[2]" is an overrun of the array. Reject such and use IWLFWCHECK instead of WARNON in this function.
