CVE-2025-48555 is a vulnerability identified in multiple functions within NotificationStation.java in Google Android versions 13 to 16. The root cause is a confused deputy problem, where the code inadvertently allows a lower-privileged local attacker to access information across different user profiles on the same device. This cross-profile information disclosure can lead to a local escalation of privilege, enabling the attacker to gain access to sensitive data or perform actions beyond their original permissions. Notably, exploitation does not require any user interaction, and no additional execution privileges are needed beyond local access, making it easier for attackers with physical or local access to the device to exploit this flaw. The vulnerability is classified under CWE-441 (Incorrect Authorization), highlighting improper access control mechanisms. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and low privileges required. While no public exploits have been reported yet, the vulnerability's nature suggests a significant risk if weaponized. The lack of available patches at the time of publication necessitates immediate attention from device manufacturers and users to mitigate potential exploitation.

For European organizations, this vulnerability poses a significant risk, especially those with employees using Android devices for work purposes or handling sensitive information on mobile platforms. The ability to escalate privileges locally and access cross-profile data could lead to unauthorized disclosure of corporate or personal data, potentially violating GDPR and other data protection regulations. The compromise of device integrity and availability could disrupt business operations, particularly in sectors such as finance, healthcare, and government, where mobile device security is critical. Furthermore, the lack of user interaction for exploitation increases the threat level, as attackers could leverage this vulnerability silently if they gain local access. This could also facilitate lateral movement within organizations if devices are shared or used in multi-profile environments. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score and broad affected Android versions indicate a widespread potential impact across Europe.

1. Monitor official Google and Android security advisories closely and apply security patches immediately once they become available to address CVE-2025-48555. 2. Until patches are released, restrict physical and local access to Android devices, especially in high-risk environments, to prevent local attackers from exploiting the vulnerability. 3. Implement strict device management policies using Mobile Device Management (MDM) solutions to enforce profile separation and limit permissions for local users. 4. Educate users about the risks of sharing devices or profiles and encourage the use of strong authentication mechanisms to reduce unauthorized local access. 5. Employ runtime protection and endpoint detection tools capable of identifying unusual privilege escalation or cross-profile access attempts on Android devices. 6. Regularly audit device configurations and installed applications to detect anomalies that could indicate exploitation attempts. 7. For organizations with BYOD policies, enforce compliance checks to ensure devices are updated and secure before granting access to corporate resources. 8. Collaborate with device vendors and service providers to prioritize patch deployment and verify remediation effectiveness.
