everyone screams microkernel when a new LPE appears but why are we not trying to fix the horrid linux permission system that even allows this to branch out into full root access?
Both dirtyfrag and copy.fail relied on a setuid binary to gain root access. Why is setuid still a thing?? The idea of letting a binary set itself to run as whatever user it wants is so backwards it should've been killed years ago but instead we let this happen every time
yes, a microkernel is the way to go for the future, but that will take a time, a very very long time, lets work on solutions to get rid of insane pitfalls like setuid first
