CVE-2026-43316 Linux内核solo6x10越界读取漏洞

/* * PoC Concept for CVE-2026-43316 * This code demonstrates the vulnerable logic: shifting a signed integer * beyond its bit width, which triggers undefined behavior. */ #include <stdio.h> #include <stdint.h> // Vulnerable function simulation void vulnerable_shift(int chip_id) { // Simulating the original code: signed "1" shifted by chip_id // If chip_id is >= 32, this is Undefined Behavior on 32-bit int int mask = 1 << chip_id; if (mask) { printf("Shift succeeded (Undefined Behavior might hide this).\n"); } } int main() { // Triggering the condition with a large chip_id // This simulates the out-of-bounds chip_id scenario int malicious_id = 64; printf("Attempting vulnerable shift with id: %d\n", malicious_id); vulnerable_shift(malicious_id); return 0; }
