This has literally happened repeatedly in the past. Just last year an exploit came to light affecting Windows XP that was so bad Microsoft had to release another security patch for it. WannaCry and NotPetya malwares used similarly severe exploits in 2017.

And given historical precedent, it’s going to be a matter of time until one is discovered.
A very long matter.
