CVE-2025-48574 is a vulnerability identified in the Android operating system, specifically affecting versions 14, 15, and 16. The issue resides in the validateAddingWindowLw method of the DisplayPolicy.java component, where a missing permission check allows a malicious application to intercept drag-and-drop events. This interception can be leveraged to perform a local elevation of privilege without requiring additional execution privileges or user interaction. The vulnerability exploits the window management subsystem, which controls how windows and UI elements are handled on the device. By bypassing permission checks, an attacker can manipulate drag-and-drop events to gain unauthorized access to higher privilege levels, potentially compromising system integrity and confidentiality. Although no public exploits have been reported yet, the flaw's nature suggests it could be exploited by malicious apps already installed on a device. The absence of a CVSS score indicates that the vulnerability is newly disclosed and pending further evaluation. The vulnerability highlights a critical gap in permission enforcement within Android's window management, emphasizing the need for rigorous validation of UI event handling to prevent privilege escalation attacks.

The primary impact of CVE-2025-48574 is the local elevation of privilege on affected Android devices, which can undermine the confidentiality and integrity of the system. An attacker with a malicious app installed can exploit this flaw to gain higher privileges without user consent or interaction, potentially allowing unauthorized access to sensitive data or system functions. This could lead to further attacks such as installing persistent malware, bypassing security controls, or accessing restricted resources. Since exploitation does not require additional execution privileges or user interaction, the attack surface is broad for any app with basic permissions. The vulnerability affects Android versions 14 through 16, which are widely deployed globally, impacting millions of devices in consumer, enterprise, and government environments. The lack of known exploits in the wild currently limits immediate risk, but the potential for stealthy privilege escalation makes this a significant threat that could be leveraged in targeted attacks or widespread campaigns if weaponized.

1. Apply official security patches from Google as soon as they become available for Android versions 14, 15, and 16. 2. Restrict app permissions related to window management and drag-and-drop operations, limiting which apps can create or intercept window events. 3. Employ mobile device management (MDM) solutions to control app installations and enforce strict permission policies. 4. Monitor device behavior for unusual window event handling or privilege escalation attempts using endpoint detection and response (EDR) tools tailored for mobile platforms. 5. Educate users and administrators about the risks of installing untrusted applications, especially those requesting extensive UI or window management permissions. 6. Encourage developers to follow secure coding practices by validating all permission checks rigorously in UI event handling code to prevent similar vulnerabilities. 7. Use application whitelisting to prevent unauthorized apps from running on sensitive devices. 8. Conduct regular security audits and penetration testing focusing on privilege escalation vectors within the Android environment.
