From the Twitter advisory on the issue being referenced here [1]:
>>> To every other developer: we believe this is a sober reality of the new AI paradigm. AI-assisted code review can now find latent bugs at a speed that is outpacing even the industry’s most seasoned experts. If your firmware is open-source or has ever been public, assume it's already being read by attackers and defenders alike.
Kinda turns the “many eyes” principle of OSS on its head, eh?
If the industry most seasoned experts are not using LLMs right now to front-run the discovery of vulnerabilities in the code they are responsible for, they are not experts, but clowns.
If your source is not open that's barely a speedbump, given a binary. At least that's my impression of the current state.
