The problem with this kind of thing, is that it reduces the S/N (Signal-to-Noise) ratio, so weeding out the legit CVEs becomes a lot more difficult. But, on the other hand, I do know that LLMs have been discovering a lot of legit CVEs, and I will lay odds that the blackhats are leveraging them to the max.
The vast majority of CVEs are not exploitable, basically noise. I suspect that the overwhelming majority of the CVEs being generated by LLMs are either noise of the sort in the linked article or noise of the sort that is not exploitable.
I suppose all these fake issues and the many more that have absurdly elevated severities could be considered an attack on the system itself, stripping it of credibility.
