For your case, they are likely just different consequences of a same memory error. Let's assume it is a use-after-free, the behavior is UAF is undefined: If that memory freed by kernel is also unmapped from kernel address space, you would get a page fault when using it afterward, that is an Oops. Or if that memory freed by kernel gets reallocated and remapped as read-only, you would get a general protection error when you writing to it afterward. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
