CVE-2026-43122 Linux内核ACPI处理器空指针漏洞

/* * Conceptual PoC for CVE-2026-43122 * This code attempts to trigger the vulnerable path by interacting with ACPI processor states. * Triggering the NULL pointer dereference depends on specific kernel state and hardware. */ #include <stdio.h> #include <stdlib.h> #include <unistd.h> int main() { printf("[+] Attempting to trigger ACPI processor idle state logic...\n"); // In a real scenario, this might involve specific sysfs writes or module loads // that force the kernel to re-evaluate processor states. // The vulnerability occurs internally in __acpi_processor_start. printf("[*] Vulnerability is triggered during kernel initialization or state change."); printf("[!] If vulnerable, the kernel will crash due to NULL pointer dereference."); return 0; }
