CVE-2026-43219: Linux内核cpsw_new驱动逻辑错误致崩溃

/* * PoC Concept for CVE-2026-43219 * Triggering the error path in cpsw_register_ports */ #include <linux/module.h> #include <linux/netdevice.h> // This is a conceptual trigger. In a real scenario, // one would need to load the cpsw_new driver and force // a registration failure on the first port. int init_module(void) { printk(KERN_INFO "Attempting to trigger CPSW vulnerability\n"); // Logic to bind device and force register_netdev() failure // would go here. This requires specific hardware or emulation. return 0; } void cleanup_module(void) { printk(KERN_INFO "Cleaning up\n"); }
