# google android: In onCreate of WindowState.java, there is a possible way to launch a background activity due to a logic error in the…

Android Framework contains an unspecified flaw that lets a local app gain higher privileges on the device. An attacker who gets a malicious app onto a phone can escalate to system-level control, and CISA lists it as exploited in the wild.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Android Framework affected ? fixed ?
- vendor:google android affected = 11.0 fixed ?
- vendor:google android affected = 12.0 fixed ?
- vendor:google android affected = 12.1 fixed ?
- vendor:google android affected = 13.0 fixed ?

## How to check

Check the Android security bulletin for the device's patch level (Settings > About phone > Android security update) against the July 2023 bulletin.

## Fix

Install the Android security update that includes the July 2023 patch level or later, per vendor instructions.
Discontinue use of unpatched devices if mitigations are unavailable, as CISA directs.

## From the sources

In onCreate of WindowState.java, there is a possible way to launch a background activity due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
