CVE-2026-23365: Linux内核kalmia驱动拒绝服务漏洞

# PoC Concept: Malicious USB Device Descriptor (Python/Example) # This simulates a device that triggers the lack of endpoint validation. # Requires a USB Gadget framework or hardware simulator to run. import usb.core import usb.util # This is a conceptual representation of a malicious device interaction. # Actual exploitation requires a hardware device or USB gadget simulation. def simulate_malicious_device(): # In a real exploit, this would be a physical device or gadgetfs setup # presenting a Kalmia device class with 0 endpoints. print("Simulating device probe...") print("Device Class: Kalmia") print("Endpoints: 0 (Malicious)") print("Expected driver behavior: Crash due to NULL pointer access") if __name__ == "__main__": simulate_malicious_device()
