DanglingDeviceObjectReference rule (wdm)

  • Makale

The DanglingDeviceObjectReference rule specifies that the driver calls ObDereferenceObject with the same device object pointer that IoGetAttachedDeviceReference returned.

This rule also specifies that all device object pointers that the driver referenced by calling IoGetAttachedDeviceReference are dereferenced by calling ObDereferenceObject before the driver exits. ObfDereferenceObject

Driver model: WDM

How to test

At compile time

Run Static Driver Verifier and specify the DanglingDeviceObjectReference rule.

Use the following steps to run an analysis of your code:
  1. Prepare your code (use role type declarations).
  2. Run Static Driver Verifier.
  3. View and analyze the results.
