If your CPU is crashing/unstable then yes, damage is already done, but for the few of us who bought these later just update your bios to the latest one, set intel defaults, do not overclock (I have even undervolted it a bit, but ymmv) and wait for the microcode update.
Though I do wonder if Intel isn’t just stalling for time, I do hope they are not. Didn’t wanna touch my build for next ~5 years.
