CVE-2025-71082: Linux内核btusb驱动内存管理不当导致释放后使用漏洞

# PoC for CVE-2025-71082 # Trigger use-after-free in btusb driver # This is a conceptual PoC - actual exploitation requires specific conditions import os import subprocess def trigger_uaf(): """Attempt to trigger the use-after-free condition""" # The vulnerability occurs when: # 1. btusb driver binds to multiple interfaces (INTF, ISOC, DIAG) # 2. Disconnect is called on one interface # 3. devm frees the data while other interfaces still reference it # In practice, this would be triggered by: # - Plugging in a Bluetooth USB device # - The driver binds to multiple interfaces # - One interface is disconnected # - Other interfaces try to access freed memory print("CVE-2025-71082 - btusb use-after-free") print("This vulnerability is triggered through normal device disconnect") return True if __name__ == "__main__": trigger_uaf()
