Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: validate bsscfg indices in IF events
brcmf_fweh_handle_if_event() validates the firmware-provided interface
index before it touches drvr->iflist[], but it still uses the raw
bsscfgidx field as an array index without a matching range check.
Reject IF events whose bsscfg index does not fit in drvr->iflist[]
before indexing the interface array.
[add missing wifi prefix]
