Okay, I see — it’s more of a case-by-case type of thing once you’ve identified a problem.
Yes, and generally as soon as a problem was detected the net became filled with pointers to the fix so as to solve the problem ASAP.
If it is a well-known/historical problem, the fix has been posted and archived, so a bit of searching will get you where you need to be.
If it is indeed a new problem, it needs to be posted about and then the various coders will have a look and get to work on the problem -and you will have identified a problem that can possibly affect many other users so you have then begun the correction process.
