CVE-2025-21003 is a medium-severity vulnerability identified in Samsung Mobile Devices related to the insecure storage of sensitive information within the Emergency SOS feature. Classified under CWE-922 (Insecure Storage of Sensitive Information), this vulnerability allows local attackers to access sensitive data stored insecurely on the device. The issue affects Samsung Mobile devices prior to the SMR (Security Maintenance Release) July 2025 Release 1 update. The vulnerability does not require any privileges or user interaction to exploit (AV:L/AC:L/PR:N/UI:N), indicating that an attacker with local access to the device—such as through physical possession or local compromise—can retrieve sensitive information without authentication. The CVSS v3.1 base score is 4.0, reflecting a limited impact primarily on confidentiality, with no impact on integrity or availability. The Emergency SOS feature typically stores critical user information to facilitate emergency response, so improper storage could expose personal or medical data. No known exploits are currently reported in the wild, and no patches or updates are linked yet, though the vulnerability is addressed in the upcoming SMR Jul-2025 Release 1. The lack of affected version details suggests the issue may be widespread across multiple Samsung Mobile device models released before this update. Overall, this vulnerability highlights a weakness in secure data handling practices within a critical safety feature on Samsung devices, potentially exposing sensitive user information to local attackers.

For European organizations, the impact of CVE-2025-21003 depends largely on the use of Samsung Mobile devices within their workforce and the sensitivity of data stored or accessible via the Emergency SOS feature. Organizations with employees who carry Samsung devices for business purposes may face risks of sensitive personal or emergency-related information leakage if devices are lost, stolen, or accessed by unauthorized personnel locally. While the vulnerability does not allow remote exploitation, the risk of data exposure in scenarios involving physical device compromise is significant. This could lead to privacy violations under GDPR if personal data is exposed, resulting in regulatory penalties and reputational damage. Additionally, emergency-related data leakage could undermine employee safety protocols or expose medical information. The vulnerability does not directly threaten system integrity or availability, so operational disruption is unlikely. However, organizations in sectors with high privacy requirements—such as healthcare, finance, or government—should be particularly cautious. The absence of known exploits reduces immediate risk, but the vulnerability should be addressed proactively to prevent future exploitation.

To mitigate CVE-2025-21003, European organizations should: 1) Ensure all Samsung Mobile devices are updated promptly to the SMR July 2025 Release 1 or later, which addresses this vulnerability. 2) Enforce strict physical security controls to prevent unauthorized local access to devices, including device lock policies, secure storage, and employee training on device handling. 3) Implement mobile device management (MDM) solutions that can enforce encryption and restrict access to sensitive features like Emergency SOS data. 4) Regularly audit devices for compliance with security policies and verify that sensitive data is not stored insecurely. 5) Educate users about the risks of local data exposure and encourage immediate reporting of lost or stolen devices. 6) Consider disabling or limiting Emergency SOS features if they are not critical to business operations until devices are patched. 7) Monitor for any future advisories or exploit reports related to this vulnerability to respond swiftly. These steps go beyond generic advice by focusing on the specific vector of local access and the nature of the Emergency SOS feature.
