Is it just the UE Oodle compression that is exposing the flaws or are non-gaming workloads affected?

Anything that pushes the CPUs significantly can cause instability in affected parts. I think there are at least two separate issues Intel is facing:

Voltage irregularities causing instability. These could potentially be fixed by the microcode update Intel will be shipping in mid-August.
Oxidation of CPU vias. This issue cannot be fixed by any update, any affected part has corrosion inside the CPU die and only replacement would resolve the issue.

Intel's messaging around this problem has been very slanted towards talking as little as possible about the oxidation issue. Their initial Intel community post was very carefully worded to make it sound like voltage irregularity was the root cause, but careful reading of their statement reveals that it could be interpreted as only saying that instability is a root cause. They buried the admission that there is an oxidation issue in a Reddit comment, of all things. All they've said about oxidation is that the issue was resolved at the chip fab some time in 2023, and they've claimed it only affected 13th gen parts. There's no word on which parts number, date ranges, processor code ranges etc. are affected. It seems pretty clear that they wanted the press talking about the microcode update and not the chips that will have the be RMA'd.
