Government agencies probably already have half of these exploits in their private toolbox for years now. Finding and patching them is good, but there probably needs to be some systematic change to prevent them rather than just patching bugs when they get found.
- FriedFishes 6mo ago> for years now ZCRX is less than half a year old. I'm so tired boss.
- onjectic 6mo agoSomething something microkernels + capability-based security.
- mattstir 6mo agoI've seen microkernels mentioned a few times between these LPE posts and I'm curious about why. Would they be fundamentally more secure against forgetting to add bounds checking, or assuming user-provided input buffers should be writable without checking?
- Gigachad 6mo agoYes, because as a userspace program if you forget to do bounds checking or read the wrong thing, the kernel kills the process. But if the buggy code is the kernel then there’s no protection. Microkernels aim to have as little code as required in kernel space.
