CVE-2026-28890 Xcode越界读取漏洞

// PoC for CVE-2026-28890 (Conceptual) // This code demonstrates a buffer over-read scenario causing a crash. #include <stdio.h> #include <stdlib.h> #include <string.h> void simulate_oob_read() { char small_buffer[10]; char large_data[100]; memset(large_data, 'A', sizeof(large_data)); // Vulnerability: Copying more data than the buffer can hold or reading beyond bounds // In a real scenario, this would be inside a parsing function of Xcode printf("Attempting to read out of bounds...\n"); // Simulating the read that causes system termination strncpy(small_buffer, large_data, 100); // OOB write/read trigger printf("Buffer: %s\n", small_buffer); } int main() { simulate_oob_read(); return 0; }
