Is this a bug from lscpu? How to fix it?

~$ lscpu

Address sizes:                   46 bits physical, 48 bits virtual
CPU(s):                          20

Model:                           151
Model name:                      12th Gen Intel(R) Core(TM) i7-12700
Stepping:                        2

This is an Intel i7-12700, it lists the CPU max MHz is 6300.0000 However, I checked the Intel website, and it lists:
