CVE-2026-31544: Linux内核arm_scmi空指针解引用漏洞

// Conceptual Proof of Concept for CVE-2026-31544 // This PoC demonstrates the logic to trigger the NULL dereference. // Requires a vulnerable Linux kernel version. #include <stdio.h> #include <stdlib.h> // In a real exploit scenario, this would involve specific interactions // with the SCMI (System Control and Management Interface) to force // the notify error path where the handler is NULL. int main() { printf("Attempting to trigger CVE-2026-31544\n"); // Simulate triggering the event handler lookup failure // In kernel space: ptr = __scmi_event_handler_get_ops(...); // If ptr is NULL and used -> Crash // Actual trigger would require specific hardware/driver interaction return 0; }
