A specific fab had a process issue, that appears to have been rectified in April 2024. Intel 4 is not affected. Other fabs making Intel 7 Ultra is not affected. The issue only noticeably shows up in the highest-end processors, and dropping max clock multiplier by ~3% seems to fix things. It's not a good thing, but it's not doomsday. The earliest Ryzens 1000s had issues with making incorrect calculations in certain circumstances, and look where they are now. More recently, just a year ago, certain Ryzen mobos literally fried their chips to ~1000 degrees (literally 1000 celsius). Yes, there are reports of ~50% failure rates, etc... but if you get a shipment of a contaminated batch, it's probably gonna fail, and a single source shouldn't be used to generalise.
