CVE-2025-58483 is a vulnerability classified under CWE-926 (Improper Export of Android Application Components) found in Samsung's Galaxy Store application for Galaxy Watch devices prior to version 1.0.06.29. The flaw arises because certain Android components within the Galaxy Store app are improperly exported, meaning they are accessible to other applications or processes without adequate access controls. This misconfiguration allows a local attacker—someone with physical or logical access to the Galaxy Watch device—to exploit these exported components to install arbitrary applications onto the Galaxy Store. The attacker does not require any privileges or user interaction to perform this installation, which could lead to unauthorized apps being installed silently. The vulnerability affects the confidentiality, integrity, and availability of the device by potentially allowing malicious apps to access sensitive data, modify device behavior, or disrupt normal operations. The CVSS v3.1 score of 5.9 reflects a medium severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L). There are no known exploits in the wild at the time of publication, and no patches or updates are explicitly linked, but upgrading to version 1.0.06.29 or later is implied as the remediation. The vulnerability was reserved in early September 2025 and published in December 2025.

For European organizations, this vulnerability poses a risk primarily to employees or users who utilize Samsung Galaxy Watch devices with the vulnerable Galaxy Store app. Unauthorized installation of arbitrary applications could lead to data leakage, unauthorized access to corporate resources, or the introduction of malware that compromises device integrity or availability. Since the attack requires local access, the risk is higher in environments where devices may be physically accessible to attackers, such as shared workspaces or public areas. The impact on confidentiality and integrity is medium, as malicious apps could access sensitive information or alter device behavior. Availability impact is also present but limited. Organizations relying on wearable technology for workforce productivity, health monitoring, or secure communications could face operational disruptions or data breaches if this vulnerability is exploited. The lack of known exploits reduces immediate risk, but the potential for future exploitation necessitates proactive mitigation.

1. Update the Galaxy Store app on all Galaxy Watch devices to version 1.0.06.29 or later as soon as it becomes available to ensure the vulnerability is patched. 2. Implement strict physical security controls to prevent unauthorized local access to wearable devices, including secure storage and device lock policies. 3. Enforce device management policies that restrict installation of applications from untrusted sources and monitor for unauthorized app installations. 4. Educate users about the risks of leaving devices unattended and the importance of reporting lost or stolen devices promptly. 5. Utilize Mobile Device Management (MDM) solutions capable of managing wearable devices to enforce security policies and monitor device compliance. 6. Regularly audit installed applications on Galaxy Watches within the organization to detect any unauthorized or suspicious apps. 7. Coordinate with Samsung support channels for timely updates and security advisories related to Galaxy Watch devices and their applications.
