Android Framework Elevation of Privilege Vulnerability in Accessibility Service Connection

A logic error in the AccessibilityServiceConnection component of the Android Framework can lead to unintended background activity launches. This vulnerability allows for local elevation of privilege, as it could be exploited without any additional execution privileges or user interaction. The issue is present in multiple Android versions, including 13, 14, and 15.

Impact

Exploitation of this vulnerability could result in unauthorized access to elevated privileges, allowing a user to perform actions or access resources that are normally restricted.

Reproduction

The vulnerability can be reproduced by binding an accessibility service that returns null in the onBind() method. This will cause the service to remain bound by the system, enabling it to launch activities from the background. After applying the patch, this behavior is no longer allowed.

Remediation

Users can update their devices to the June 2025 security patch level to address this vulnerability.
