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.
