In the Linux kernel, the following vulnerability has been resolved:

wifi: wfx: validate MIB read length before copying to caller

wfx_hif_read_mib() copies reply->length bytes from the firmware
response into the caller-provided buffer without checking that
reply->length does not exceed val_len. A firmware response with
a length field larger than expected overruns the caller buffer and
reads past the end of the reply allocation.

Replace the dead -ENOMEM check with an active validation that
reply->length fits within val_len before the memcpy.
