CVE-2025-48598 is a privilege escalation vulnerability identified in Google Android version 16, specifically related to the face unlock biometric authentication feature. The root cause is a confused deputy problem, where multiple system components improperly handle permissions, allowing an attacker to alter the primary user's face unlock settings. This manipulation can effectively bypass biometric security controls, granting physical escalation of privilege without requiring the attacker to have additional execution privileges or any user interaction. The vulnerability exists in multiple locations within the Android system, indicating a systemic issue in how biometric settings permissions are enforced. Although no exploits have been observed in the wild, the potential impact is significant because face unlock is a common and trusted method for device access. The vulnerability was reserved in May 2025 and published in December 2025, but no CVSS score has been assigned yet. The lack of user interaction and no need for elevated privileges to exploit this vulnerability increase its risk profile. This vulnerability undermines the integrity and confidentiality of the device's security mechanisms, potentially allowing unauthorized users to gain physical access to sensitive data and applications protected by biometric authentication.

For European organizations, this vulnerability poses a substantial risk to mobile device security, particularly for employees using Android 16 devices with face unlock enabled. Unauthorized alteration of face unlock settings could allow attackers to bypass biometric authentication, leading to unauthorized access to corporate data, internal networks, and sensitive applications. This could result in data breaches, intellectual property theft, and compromise of user privacy. The impact is heightened in sectors relying heavily on mobile device security, such as finance, healthcare, and government agencies. Additionally, the vulnerability could facilitate lateral movement within corporate environments if compromised devices are used as entry points. The absence of required user interaction or additional privileges makes remote or local exploitation easier, increasing the threat surface. The overall availability of Android devices in Europe means a broad range of organizations could be affected, especially those with bring-your-own-device (BYOD) policies or mobile-first workforces.

Organizations should prioritize monitoring for updates and patches from Google addressing CVE-2025-48598 and apply them promptly once released. Until patches are available, restricting access to biometric settings through device management policies can reduce the risk of unauthorized changes. Employing Mobile Device Management (MDM) solutions to enforce strict controls on biometric configuration and usage is recommended. Additionally, organizations should consider temporarily disabling face unlock on critical devices or for high-risk users until the vulnerability is mitigated. Educating users about the risks and encouraging the use of multi-factor authentication methods beyond biometrics can provide additional security layers. Regular audits of device security settings and logs for unusual changes to biometric configurations can help detect exploitation attempts. Finally, organizations should review and tighten permissions related to biometric settings within their Android device management frameworks.
