It is possible to overflow cpufreq_info::name and cpufreq_info::sysfs_filename
inside add_object function. It require to somehow(ex. inside chroot) create
custom directory inside `/sys/devices/system/cpu/` named like
cpu0<custom_data_here>` and it will pass:
if (sscanf(dp->d_name, "cpu%d\n", &cpu_index) != 1)
continue;
