No, we don't have access to the data sheets. This is the exact same
bug as the following patches:
381583845d19 ("HID: cp2112: prevent a buffer overflow in cp2112_xfer()")
690b2549b195 ("i2c: ismt: prevent memory corruption in ismt_access()")
The patch should fix the memory corruption but there may be other issues
with this code.
