The invalid data that may be read comes from a ROM in the SoC,
programmed by the vendor, and is only used to configure CPU frequency
and voltage in the cpufreq framework.

Even assuming that improper frequency/voltage settings constitute a
security risk, writing to the ROM in question is at least a privileged
operation, and may require physical access to the SoC.

I don't think this qualifies as vulnerability.
