CVE-2025-21024 is a vulnerability identified in Samsung Mobile's Smart View application, specifically affecting versions prior to Android 16. The issue stems from the use of implicit intents for sensitive communication within the app. Implicit intents in Android allow components to request actions from other components without specifying the exact target, which can lead to unintended recipients receiving sensitive data. In this case, local attackers with limited privileges (PR:L) can exploit this design flaw to access sensitive information transmitted via these implicit intents. The vulnerability does not require user interaction (UI:N) and has a low attack complexity (AC:L), but the attack vector is local (AV:L), meaning the attacker must have local access to the device. The impact is limited to confidentiality (C:L) with no impact on integrity or availability. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability is classified under CWE-927, which relates to the use of implicit intent for sensitive communication, highlighting a design weakness in inter-component communication security within the Android ecosystem. The CVSS score is 3.3, indicating a low severity level, reflecting the limited scope and impact of the vulnerability.

For European organizations, the impact of this vulnerability is relatively low but should not be dismissed. Samsung devices are widely used across Europe, including in corporate environments where Smart View may be employed for screen sharing and media streaming. A local attacker, such as an insider or someone with physical access to a device, could potentially extract sensitive information from the Smart View app due to this flaw. While the vulnerability does not allow remote exploitation or affect system integrity or availability, the confidentiality breach could expose sensitive corporate data or personal information. This is particularly relevant in sectors with strict data protection regulations like GDPR, where even limited data leakage can have compliance and reputational consequences. However, the requirement for local access and the absence of user interaction reduce the likelihood of widespread exploitation. Organizations should consider this vulnerability in their device security assessments, especially those with Samsung mobile devices used in sensitive roles or environments.

To mitigate CVE-2025-21024, European organizations should take several specific steps beyond generic advice: 1) Enforce strict physical security controls to prevent unauthorized local access to devices, including secure storage and device lock policies. 2) Limit the use of Smart View on devices handling sensitive information or restrict its functionality via mobile device management (MDM) solutions. 3) Monitor and audit device usage to detect any unusual local activity that could indicate exploitation attempts. 4) Encourage users to update their devices to Android 16 or later once available, as the vulnerability affects versions prior to Android 16. 5) Engage with Samsung for timely patches or updates addressing this issue and deploy them promptly. 6) Educate users about the risks of local device access and the importance of not leaving devices unattended in unsecured environments. These targeted measures will help reduce the risk posed by this vulnerability in operational environments.
