I recall this debacle; the patch to address this (aka disable undervolting) caused a huge furore at forum.notebookreview.com (which has since closed; what a pity), which was full of enthusiasts undervolting and overclocking their notebook CPUs and GPUs. It is worth noting that CPU undervolting gives a roughly 15±5% performance boost to all notebooks with modern Intel CPUs (Haswell and later), while keeping power draw the same—one might understand why enthusiasts were irritated by the patch. My previous Dell notebook was issued firmware updates[0] for this CVE: CVE-2019-11157. However, the 'bug' was never properly patched, and resetting the firmware to factory defaults after an upgrade could restore undervolting. In my current notebook (also a Dell: Precision 7560), undervolting is disabled to begin with, but it may be restored by modifying UEFI variables[1].
