In the Linux kernel, the following vulnerability has been resolved:
wifi: carl9170: bound memcpy length in cmd callback to prevent OOB read
When the firmware sends a command response with a length mismatch, carl9170_cmd_callback() logs the mismatch and calls carl9170_restart() but then falls through to memcpy(ar->readbuf, buffer + 4, len - 4). Since len comes from the firmware and can exceed ar->readlen, this copies more data than the readbuf was allocated for.
Bound the memcpy to min(len - 4, ar->readlen) so that the response is still completed -- avoiding repeated restarts from queued garbage -- while preventing an overread past the response buffer.
