They said the cause was a bug in the microcode making the CPU request unsafe voltages:

Our analysis of returned processors confirms that the elevated operating voltage is stemming from a microcode algorithm resulting in incorrect voltage requests to the processor.

If the buggy behaviour of the voltage contributed to higher boosts, then the fix will cost some performance. But if the clocks were steered separately from power, and the boost clock is still achieved without the overly high voltage, then it might be performance neutral.

I think we will know for sure soon, multiple reviewers announced they were planning to test the impact.

Thanks for the clarification
