kfd

简要免责声明：我无意添加对其他设备和 iOS 版本的偏移量。 kfd kfd，即 kernel file descriptor（内核文件描述符）的缩写，是一个在 Apple 设备上读写内核内存的项目。它利用各种可利用的漏洞来获取悬空 PTE（页表项），这被称为 PUAF 原语，即 physical use-after-free（物理释放后使用）的缩写。然后，它会在这些物理页内重新分配某些内核对象，并通过悬空 PTE 从用户空间直接操纵它们，以实现 KRKW 原语，即 kernel read/write（内核读写）的缩写。漏洞利用代码完全包含在一个库 libkfd 中，但该项目还包含针对...
