CVE-2026-20984 is a vulnerability identified in Samsung's Galaxy Wearable application, specifically affecting installations on non-Samsung devices prior to version 2.2.68. The root cause is improper handling of insufficient permissions (CWE-280), which means the application fails to correctly enforce permission checks when accessing sensitive information. This flaw allows a local attacker—someone with physical or local access to the device—to bypass permission restrictions and retrieve sensitive data stored or accessible via the Galaxy Wearable app. The vulnerability does not require any authentication or user interaction, increasing the risk if an attacker gains local access. The CVSS 4.0 base score is 5.1 (medium severity), reflecting that the attack vector is local (AV:L), with low complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and limited confidentiality impact (VC:L). The vulnerability does not affect integrity or availability. There are no known exploits in the wild, and no official patches or updates have been linked yet, though the fixed version is identified as 2.2.68 or later. This vulnerability is particularly relevant for users running the Galaxy Wearable app on non-Samsung Android devices, which may be common in diverse enterprise environments. The improper permission handling could lead to unauthorized disclosure of sensitive information related to wearable devices, such as health data or device configurations.

For European organizations, the primary impact of CVE-2026-20984 is the potential unauthorized disclosure of sensitive information through the Galaxy Wearable app on non-Samsung devices. This could include personal health data, device pairing information, or other confidential user data managed by the wearable ecosystem. Such data leakage could lead to privacy violations, regulatory non-compliance (e.g., GDPR), and reputational damage. The vulnerability requires local access, so the risk is higher in environments where devices are shared, lost, or physically accessible by unauthorized personnel. The medium severity score reflects moderate risk; however, in sectors like healthcare, finance, or government where sensitive wearable data might be used, the impact could be more significant. Since no known exploits exist yet, the immediate threat is limited, but the vulnerability should be addressed proactively. The lack of integrity or availability impact reduces the risk of operational disruption but does not diminish the confidentiality concerns. Organizations using Galaxy Wearable on non-Samsung devices should assess their device management policies and physical security controls to mitigate risk.

1. Update the Galaxy Wearable app to version 2.2.68 or later as soon as the patch is available from Samsung to ensure proper permission handling. 2. Restrict physical and local access to devices running the vulnerable app, especially in shared or public environments, to reduce the risk of local exploitation. 3. Implement mobile device management (MDM) solutions to monitor app versions and enforce update policies across organizational devices. 4. Educate users about the risks of installing Galaxy Wearable on non-Samsung devices and encourage use on supported Samsung hardware where possible. 5. Monitor for unusual local access or data access patterns on devices with the app installed. 6. Consider restricting installation of Galaxy Wearable on non-Samsung devices via enterprise app policies until the vulnerability is patched. 7. Review and audit sensitive data stored or accessible via the wearable app to minimize exposure. 8. Maintain up-to-date endpoint security solutions that can detect suspicious local activity related to app misuse.
