Description Alex 2022-12-05 17:37:35 UTC 
A flaw array-index-out-of-bounds in the Linux Kernel found in drivers/net/wireless/broadcom/brcm80211/brcmfmac/fweh.c. When attaching malicious USB device, buffer overflow could happen in the Broadcom Full MAC Wi-Fi driver. The bug occurs in brcmf_fweh_event_worker, when emsg.bsscfgidx, data from an URB provided by a USB device, is bigger than the size of the array drvr->iflist.
