My take is based on pretty nuanced analysis of hundreds of CVEs over the past few years.
A common 'vulnerability' area that I find dubious is that some utility can be made to crash instead of exiting cleanly. Usually the rationale is that "imagine someone is using this in a kiosk-like context and they can crash out unexpectedly to a shell".... For utilities like wget and such that would never ever be in such a position. Even if such a kiosk application existed, the utility would crash back into the calling utility, and hard to imagine that sort of Kiosk design this century anyway.
Or things like "if an attacker just gets you to run this 4GB "script" in vim script then it could run arbitrary code... Except vim script can already run arbitrary commands already by design, so if a user would just run a script blindly, then just malicious commands would be so much easier. If a human does double-check, then the 4GB is even more suspicious than a script with commands. This isn't about issues that are exploitable but not exploited, this is about issues that as far as anyone can figure are not realistically exploitable in the first place.
One vulnerability in curl was that you could pass arguments to get curl to emit c code (but not compile it or run it), and someone could get it to emit arbitrary C code. So the attack scenario would be "you have a user who is somehow allowed to run curl and a compiler but not run anything else and be able to write the intermediate C file". I cannot imagine a situation where the user has free control to curl arguments but cannot simply write a file and also be able to invoke a compiler without having some other more trivial way to write a c file first.
Note that I'm not talking about AI specifically, AI is just continuing the trend. The security industry has long had a human issue that makes people understandably be a bit dismissive of CVEs at first glance because Wolf is cried just constantly. A "security researcher" finds a bug, particularly one where the user has to be explicitly trying to use it wrong, and get a CVE issued instead of accepting it may be "just a bug".
You have CVEs that are very real and very severe. But by the numbers, most of them are like the above, where someone has to invent pretty stupid scenarios in order to fairly consider it a security issue.
