CVE-2026-20447 GenieZone权限提升漏洞

/* * Conceptual Proof of Concept for Missing Bounds Check * This demonstrates the concept of accessing memory outside allocated buffer bounds. */ #include <stdio.h> #include <stdlib.h> void vulnerable_function(char* input, int size) { char buffer[10]; // Missing bounds check here: copying 'size' bytes into a 10-byte buffer for (int i = 0; i < size; i++) { buffer[i] = input[i]; // Potential buffer overflow if size > 10 } printf("Buffer processed.\n"); } int main() { char large_input[20]; // Simulate attacker-controlled input for(int i=0; i<20; i++) large_input[i] = 'A'; // Trigger the vulnerability with size larger than buffer vulnerable_function(large_input, 20); return 0; }
