What vulnerabilities have been found in Bitcoin Core using fuzzing? Is there a list of vulnerabilities that have been found in Bitcoin Core using fuzz testing?
For a list of historical Bitcoin related CVEs (common vulnerabilities and exposures) see the Bitcoin wiki.
However, for a focus on Bitcoin Core vulnerabilities found by fuzzing there is a resource on the Bitcoin Core dev wiki on &quot;fuzz trophies&quot;.
Marco Falke stated here in May 2021:

I did a survey of all bugs found first by fuzzing, excluding known
bugs that can merely be reproduced by fuzzing (regression fuzz
testing). I found that most bugs fall into one of the categories:

Silent merge conflict (forgetting to update the fuzz target after code changes)
A bug in the fuzz target itself
A recently introduced critical (exploitable) bug, but only present in    the master main development branch
A minor (non-exploitable) bug, potentially present in previous    releases
