CVE-2025-48602 is a logic error vulnerability located in the exitKeyguardAndFinishSurfaceBehindRemoteAnimation method of the KeyguardViewMediator.java component in Google Android versions 14, 15, and 16. The vulnerability allows an attacker to bypass the lockscreen mechanism due to improper handling of the lockscreen state transition, specifically in the logic controlling the finishing of surfaces behind remote animations. This flaw enables a local attacker to escalate privileges without requiring any prior execution privileges or user interaction, effectively allowing unauthorized access to the device. The vulnerability is classified under CWE-693 (Protection Mechanism Failure), indicating a failure in the security control logic. The CVSS v3.1 base score is 8.4, reflecting high severity with impacts on confidentiality, integrity, and availability (all rated high). The attack vector is local, requiring physical or local access to the device, but no authentication or user interaction is needed, increasing the risk of exploitation by malicious insiders or malware already present on the device. No known exploits have been reported in the wild as of the publication date, but the vulnerability's nature suggests it could be leveraged for unauthorized data access, device control, or persistence. The lack of available patches at the time of reporting necessitates urgent attention from device manufacturers and users to mitigate potential risks.

The vulnerability allows attackers to bypass the Android lockscreen, leading to unauthorized access to sensitive data and device functions. This can result in complete compromise of device confidentiality, integrity, and availability. Attackers could install malware, exfiltrate personal or corporate data, manipulate system settings, or disrupt device operations. For organizations, this could mean exposure of corporate data on employee devices, unauthorized access to enterprise applications, and potential lateral movement within corporate networks. The ease of exploitation without user interaction or prior privileges increases the threat level, especially in environments where devices are physically accessible or targeted by malicious insiders. The widespread use of affected Android versions globally amplifies the potential impact, making this a significant risk for both individual users and enterprises relying on Android devices for secure communications and operations.

1. Immediate deployment of official security patches from Google or device manufacturers once available is critical. 2. Until patches are released, organizations should enforce strict physical security controls to prevent unauthorized local access to devices. 3. Enable additional device security features such as biometric authentication and secure lockscreen policies to add layers of protection. 4. Monitor devices for unusual behavior indicative of privilege escalation attempts or lockscreen bypass. 5. Employ mobile device management (MDM) solutions to enforce security policies and remotely wipe compromised devices. 6. Educate users about the risks of leaving devices unattended and the importance of applying updates promptly. 7. For high-risk environments, consider restricting use of affected Android versions or deploying endpoint detection and response (EDR) tools capable of detecting exploitation attempts. 8. Collaborate with vendors to expedite patch development and distribution. These steps go beyond generic advice by emphasizing layered security, monitoring, and organizational controls tailored to the vulnerability's characteristics.
