The comments say that the product number is a 16-digit HEX string so the
buffer needs to be at least 17 characters to hold the NUL terminator. Expand
the buffer size to 20 to avoid the alignment issues.
The comment:Product number should only be 16 characters. Any
more,and something could be wrong. Cap it at 16 to be safe

If 17 is enough, why setting as 20?

That's the next multiple of 4 and so avoids alignment issues.

Well first of all you repeated the commit message twice.
Then when it is fixed 16 digit Hex string then we probably don't have a
NUL terminator in the first place.
Please double check.
