In onCreate of InstallStart.java, there is a possible package validation bypass due to a time-of-check time-of-use vulnerability. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation. Product: Android Versions: Android-8.0 Android ID: A-140195904

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
