Simple Kernel Exploit

  • kfd
    • kfd, being short for kernel file descriptor, is a project to read and write kernel memory on Apple devices. It leverages various vulnerabilities that can be exploited to obtain dangling PTEs, which will be referred to as a PUAF primitive, short for "physical use-after-free". Then, it reallocates certain kernel objects inside those physical pages and manipulates them directly from user space through the dangling PTEs in order to achieve a KRKW primitive, short for "kernel read/write".
    • kfd is a type of kernel exploit that is classified into 3 types:
  • oobPCI
    • CVE-2022-26763; this exploit can be used to read and write kernel memory
