Well, for the sake of the contrived example, let's assume that "during maintenance",

memcpy_s(buf, BUFLEN, src, len)

is changed to

memcpy_s(src, len, buf, BUFLEN)

now, there's no buffer overflow but likely a very serious memory corruption problem.

There's exactly no reason for this assumption except that's it's another way to break the working code but there wasn't any reason for your assumption, either.
