CVE-2025-48551 is a vulnerability identified in multiple locations within the Google Android operating system, specifically affecting versions 13 through 16. The issue arises from a confused deputy problem that leads to a possible leak of an image across the Android User isolation boundary. In Android, user isolation boundaries are critical for maintaining separation between different user profiles and apps, ensuring that data belonging to one user or app cannot be accessed by another without proper authorization. The confused deputy scenario here means that a privileged component is tricked into misusing its authority, resulting in unintended information disclosure. The vulnerability allows local information disclosure without requiring any additional execution privileges, meaning an attacker with local access to the device could potentially exploit this flaw. However, exploitation requires user interaction, which implies that the attacker must convince the user to perform some action, such as opening a malicious file or app. The leak involves images, which could be sensitive user data such as photos or screenshots. Although no known exploits are currently reported in the wild, the vulnerability's presence in recent Android versions makes it a relevant concern. The lack of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed in severity by standard scoring systems. The absence of patch links suggests that a fix may not yet be publicly available or is in the process of being developed.

For European organizations, this vulnerability poses a risk primarily to mobile device security and data privacy. Many organizations rely on Android devices for employee communication, data access, and business operations. The information disclosure could lead to leakage of sensitive images or data stored on employee devices, potentially exposing confidential corporate information or personal data protected under GDPR. Since the vulnerability requires local access and user interaction, the risk is somewhat mitigated by the need for physical device access or social engineering. However, targeted attacks against employees, especially those with privileged access or handling sensitive information, could exploit this flaw to gain unauthorized insights. The impact on confidentiality is significant, as leaked images could contain sensitive visual data. Integrity and availability are less affected since the vulnerability does not allow code execution or denial of service. The threat could also undermine user trust in Android devices within corporate environments, leading to increased security management overhead.

Organizations should implement several specific measures to mitigate this vulnerability: 1) Enforce strict device usage policies that limit installation of untrusted applications and restrict user actions that could lead to exploitation, such as opening unknown files or links. 2) Educate users about social engineering risks and the importance of cautious interaction with unsolicited content, especially on mobile devices. 3) Monitor for updates from Google and Android vendors, and prioritize timely patching once a fix is released. 4) Employ mobile device management (MDM) solutions to enforce security configurations, control app permissions, and remotely wipe devices if compromise is suspected. 5) Use endpoint detection and response (EDR) tools capable of monitoring anomalous local activities that could indicate exploitation attempts. 6) Limit physical access to devices and implement strong authentication mechanisms to reduce the likelihood of local exploitation. 7) Consider encrypting sensitive images and data stored on devices to reduce the impact of any information disclosure.
