the intent here isn’t to fear-, scare-monger or bait clicks. it is just to remind folks to backup their systems before updating. especially since these are most often presented with other regular package updates. apparently what started out as only affecting red hat has also now done so with some ubuntu and debian (among others) systems.
i have seen the updates on both of my ubuntu 18.04-based systems. i have not applied them yet. i did apply the update on an debian 10.4 vm that was upgrading to 10.5 and did so without bricking.
