Recommendation: Monitor — no exploitation signal at the moment.
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->smem_cfg.lmac[2]" is
an overrun of the array. Reject such and use IWL_FW_CHECK
instead of WARN_ON in this function.
