Can someone show me an example of JavaScript code running in a browser that would display a password stored in kernel space? Websites like the Guardian report

Can someone show me an example of JavaScript code running in a browser that would display a password stored in kernel space?
Websites like the Guardian report that this is now the case but I don't understand how that's possible.
- mdavidn 9y agoThe kernel maps itself into the address space of each process as an optimization to increase the performance of system calls. So yes, it is possible.
- delaaxe 9y agoSo, which functions would you have to call? How would you read the secrets? You can't do any kind of pointer magic in JS (nor system calls).
