CVE-2026-31762

/* * Conceptual PoC for CVE-2026-31762 * This describes the logic to trigger the resource leak. * Exploitation requires the vulnerable kernel module and hardware. */ #include <linux/module.h> #include <linux/platform_device.h> // Triggering the vulnerability involves forcing the iio_trigger_register to fail // after request_threaded_irq has succeeded. static int __init trigger_vuln(void) { // In a real scenario, an attacker would attempt to bind the driver // or trigger device probe while the system is in a state // where iio_trigger_register is likely to fail (e.g., memory pressure). // The vulnerability is the lack of cleanup on this error path. printk(KERN_INFO "Attempting to trigger mpu3050 probe failure...\n"); // The actual exploit is interacting with the hardware/driver interface. return 0; } static void __exit cleanup_vuln(void) { printk(KERN_INFO "Exiting...\n"); } module_init(trigger_vuln); module_exit(cleanup_vuln); MODULE_LICENSE("GPL");
