LPEs are not RCEs
They didn't say they were, the post is very clear about the the 948 vulns they're talking about being LPE.
If it’s a bunch of local jvm consoles or vi escapes into shell
if it was that, they wouldn't be "Linux LPEs". These are clearly kernel bugs they're talking about.
And again, stop taking OpenAI at their word about security.
OpenAI is full of shit about a lot of things but I doubt they're lying about having working exploits for these Linux bugs.
