What to Know

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. (NVD)

What to Do

Monitor Linux's web page for any future patch releases.
