CVE-2025-21022 is a vulnerability classified under CWE-284 (Improper Access Control) affecting Samsung Mobile's Galaxy Wearable application versions prior to 2.2.63.25042861. This vulnerability allows local attackers with limited privileges (PR:L) to access sensitive information stored or processed by the Galaxy Wearable app without requiring user interaction (UI:N). The vulnerability arises due to insufficient enforcement of access control mechanisms within the app, permitting unauthorized local access to data that should be protected. The attack vector is local (AV:L), meaning the attacker must have local access to the device, such as through a compromised user account or physical access. The vulnerability does not impact integrity or availability but results in a confidentiality breach, potentially exposing sensitive user data related to wearable device usage. The CVSS v3.1 base score is 3.3, indicating a low severity level, primarily because exploitation requires local access and only results in limited confidentiality loss without broader system compromise. No known exploits are currently reported in the wild, and no patches or updates are linked in the provided information, though the vulnerability is addressed in versions 2.2.63.25042861 and later. The vulnerability's technical root cause is improper access control, which is a common security weakness where the application fails to properly restrict access to sensitive resources or functions based on user privileges or context.

For European organizations, the impact of CVE-2025-21022 is relatively limited due to its low severity and local attack vector. However, organizations with employees or users who utilize Samsung Galaxy Wearable devices in professional environments could face confidentiality risks if an attacker gains local access to the device or the connected smartphone. Sensitive information such as health data, biometric information, or corporate data synchronized with the wearable could be exposed. While the vulnerability does not allow remote exploitation or system-wide compromise, it could facilitate insider threats or attacks following device theft or loss. In regulated sectors such as healthcare, finance, or government within Europe, even limited data exposure could lead to compliance issues under GDPR and other data protection laws. Therefore, the risk is more pronounced in environments where wearable devices are used to handle or access sensitive organizational data.

To mitigate this vulnerability effectively, European organizations should: 1) Ensure all Samsung Galaxy Wearable applications are updated to version 2.2.63.25042861 or later as soon as updates become available, as this version addresses the improper access control issue. 2) Enforce strict device access controls, including strong authentication mechanisms on both the wearable and paired smartphones, to prevent unauthorized local access. 3) Implement endpoint security solutions that monitor and restrict local privilege escalation attempts and unauthorized access to applications handling sensitive data. 4) Educate users on the risks of device theft or loss and enforce policies for immediate reporting and remote wiping of lost devices. 5) Limit the use of wearable devices for accessing or storing sensitive corporate data unless adequate security controls are in place. 6) Regularly audit and review access permissions and logs related to wearable device usage within the organization to detect suspicious activities early.
