A cache invalidation bug in Linux memory management
"This fits in with the kernel's policy of attempting to keep the system running as much as possible by default; if an accidental use-after-free bug occurs here for some reason, the kernel can probably heuristically mitigate its effects and keep the process working."That's a pretty bad design decision. I'd much rather have a kernel panic than a kernel that continues to run with known bad datastructures. Like that the bugs will never really shake out, silent failures like that are super dangerous because essentially the system is running in an undefined state past that point.
