To read and scan SMBIOS in /dev/mem is dangerous and for DMI information it will be better to read from /sys/firmware/dmi/tables/DMI if it exists.

Segmentation fault (core dumped) |
[Impact]
* Read from /dev/mem and scan DMI tables is dangerous, if /dev/mem is not stable to read, it will cause lscpu crash.
[Test Case]
* `sudo lscpu` shall not cause Segmentation fault (core dumped)
[Regression Potential]
* Reading from DMI tables is sysfs is more stable then reading from /dev/mem and if DMI tables is not available lscpu will use the old way to search in /dev/mem. I believe its low regression risk |
