Bluetooth: btintel: validate version TLV value lengths
btintel_parse_version_tlv() verifies that a complete TLV is present in
the response, but it does not ensure that the value is long enough for
the specific TLV type. A short value can therefore cause an
out-of-bounds read through get_unaligned_le16(), get_unaligned_le32(),
or memcpy().
Reject values shorter than the minimum required by each known TLV type.
Also reject responses that do not contain the Command Complete Status
field.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
