CVE-2025-48608 is a vulnerability identified in the Android operating system, specifically within the SettingsProvider.java file's isValidMediaUri method. The root cause is a missing permission check that fails to properly enforce user boundaries when accessing media URIs. This flaw allows a local attacker, without requiring elevated privileges or user interaction, to read media files belonging to other users on the same device. Android supports multiple user profiles, and this vulnerability breaks the isolation between these profiles by permitting cross-user media read access. The affected Android version is 16-qpr2, which is a recent release. The vulnerability does not require any additional execution privileges, meaning any local app or user with access to the device can exploit it. Although no public exploits have been reported, the lack of authentication or user interaction requirements increases the risk of exploitation. The vulnerability primarily impacts confidentiality by exposing potentially sensitive media data such as photos, videos, or audio files stored under different user profiles. The absence of a CVSS score suggests this is a newly disclosed issue, but the technical details indicate a significant security concern that should be addressed promptly. No patches or mitigation links are currently provided, so organizations must monitor vendor updates closely.

For European organizations, this vulnerability poses a risk to the confidentiality of sensitive media data stored on Android devices, especially those used in shared or multi-user environments such as corporate devices or kiosks. Unauthorized access to media files could lead to leakage of personal or corporate information, potentially violating data protection regulations like GDPR. The vulnerability could be exploited by malicious insiders or compromised local apps to access confidential images or recordings, undermining user privacy and organizational security. Although it does not directly affect system integrity or availability, the exposure of sensitive media content can have reputational and compliance consequences. Organizations relying on Android devices for mobile workforce or customer-facing applications should be aware of this risk and implement controls to limit local access and monitor device usage. The lack of required user interaction and privileges increases the likelihood of exploitation in environments where device physical or local access is possible.

Since no official patches are currently available, European organizations should implement the following specific mitigations: 1) Restrict local device access by enforcing strong device lock mechanisms and limiting physical access to authorized personnel only. 2) Use Mobile Device Management (MDM) solutions to control app installations and permissions, preventing installation of untrusted or potentially malicious local apps. 3) Monitor device logs and behavior for unusual access patterns to media files across user profiles. 4) Educate users about the risks of installing apps from untrusted sources and the importance of maintaining device security. 5) Segment device usage to avoid multi-user scenarios where possible, or configure user profiles with minimal privileges. 6) Stay alert for official patches or security updates from Google and apply them promptly once released. 7) Consider deploying endpoint detection and response (EDR) tools capable of detecting local privilege abuse or unauthorized media access. These steps go beyond generic advice by focusing on local access control, user education, and proactive monitoring tailored to this vulnerability's characteristics.
