In InstallPackage of package.cpp, there is a possible bypass of a signature check due to a Time of Check/Time of Use condition. This could lead to local escalation of privilege by allowing a bypass of the initial zip file signature check for an OS update with no additional execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-10Android ID: A-136498130

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.
