Preface:
Retrospective last decade, the key word so called vulnerability look like a stranger to us. But it change today. Design vulnerability, it was no doubt to say. They are the belongings of cost effective solution, market competition (short development life cycle) and satisfy human want.

Design technique – Wear leveling (also written as wear levelling) is a technique for prolonging the service life of some kinds of erasable computer storage media.

Design limitation – Wear-leveling does not guarantee that an old copy of updated data is fully removed. If the updated data is written to a new segment, old versions of data may exist in the previous segment for some time after it has been updated (until that previous segment is overwritten).

Impact – There is possible way to allow data theft to collect and read the encrypted data through physical attack (reverse engineering). A vulnerability for hardware encryption method.
