I thought copy.fail is a privelage escalation exploit, become root from a regular user? Am I missing something?
How would "node architecture" make people vulnerable to this?
You have to have shell access to a victim first right? Or am I missing something?
Yeah you need native code execution, and if you have AF_ALG access there is clearly no sandboxing in place. At that point it's game over on Linux, there are too many bugs. Even if you fix all the known ones in the current kernel, by the time the version with those fixes is qualified and released (not to mention, the machine must reboot), new LPEs have been discovered.
