Android Framework and Launcher3 Elevation of Privilege Vulnerability Allowing Background Application Launch

A vulnerability has been identified in the Android Framework and Launcher3 application, allowing for unauthorized elevation of privileges. This issue arises from a failure in precondition checks, which could enable an application to be launched from the background without user interaction. The vulnerability affects multiple Android versions and could lead to unauthorized access or actions within the application.

Impact

Exploitation of this vulnerability could result in unauthorized elevation of privileges, allowing a user to gain access to restricted functions or data within the application or system.

Reproduction

The vulnerability can be reproduced by launching an application from the background, taking advantage of the flawed precondition checks that fail to properly validate the application's launch request. This can be done by sending a command that triggers the launch of the application while it is not in the foreground, bypassing the usual user interaction requirements.

Remediation

Users can update to the December 2025 security patch level to address this vulnerability.
