I have yet to see one on any project I’ve been attached to that was actually exploitable under real circumstances. But the CVE hunting teams treat them all as if they were.
TFA is about Project Zero getting uppity about an unexploitable non-issue in ffmpeg.
Project Zero hasn't reported any vulnerabilities in any software I maintain. Lots of other security groups have, some well respected as well, but to my knowledge none of these "outside" reports were actual vulnerabilities when analyzed in context.
You are welcome to view the report however you like, but a world where an easily reproducible OOB read and UAF in the default configuration is an "unexploitable non-issue" is not reality.
