CVE-2025-58482 Overview
CVE-2025-58482 is an improper access control vulnerability in the MPLocalService component of Samsung MotionPhoto. Versions prior to 4.1.51 fail to properly restrict access to a privileged service, allowing local attackers to start it without adequate authorization. Successful exploitation can lead to high impact on confidentiality, integrity, and availability of the affected device. The issue requires local access, low privileges, and user interaction, which limits remote exploitation scenarios but still exposes users to malicious apps installed on the device.
Critical Impact
A local attacker with a low-privileged foothold can start a privileged Samsung MotionPhoto service and gain elevated access to sensitive functions on the device.
Affected Products
- Samsung MotionPhoto versions prior to 4.1.51
- Android devices with vulnerable MPLocalService component installed
- Samsung mobile ecosystems bundling the affected MotionPhoto application

Technical Details for CVE-2025-58482
Vulnerability Analysis
The vulnerability resides in MPLocalService, an internal Samsung MotionPhoto service designed to handle motion photo processing tasks. The service exposes an interface that does not enforce sufficient access checks against calling applications. A local application on the device can invoke the service and cause it to run with elevated privileges normally reserved for trusted Samsung components. Because MotionPhoto handles media content that spans camera, gallery, and file storage subsystems, elevated access can translate into broader compromise of user data and device state. The vendor addressed the flaw in Samsung MotionPhoto version 4.1.51.
Root Cause
The root cause is improper access control on the MPLocalService interface. The service does not properly verify that the calling process is authorized to start privileged operations, allowing any local app to trigger functionality that should be restricted to trusted callers.
Attack Vector
An attacker must first install or run a malicious application on the target device. The application then invokes MPLocalService and triggers user interaction to complete the exploit chain. Once the privileged service starts on behalf of the untrusted caller, the attacker can abuse its functionality to affect confidentiality, integrity, and availability. Details of the exploitation technique were not published. Refer to the Samsung Security Update for vendor-provided technical context.
Detection Methods for CVE-2025-58482
Indicators of Compromise
- Unexpected invocations of MPLocalService originating from non-Samsung or newly installed applications
- Presence of untrusted APKs that reference MotionPhoto components or intents
- Abnormal MotionPhoto processes running with elevated permissions outside normal media-capture workflows
Detection Strategies
- Inventory installed Samsung MotionPhoto versions across managed devices and flag any below 4.1.51
- Monitor mobile threat defense telemetry for applications binding to Samsung MotionPhoto services
- Correlate installation of unknown third-party apps with subsequent access to privileged Samsung services
Monitoring Recommendations
- Enable enterprise mobility management (EMM) policies that report application inventory and version data
- Alert on installations from unknown sources on devices that store sensitive corporate data
- Track Samsung Security Maintenance Release (SMR) status to confirm devices receive the December 2025 update
How to Mitigate CVE-2025-58482
Immediate Actions Required
- Update Samsung MotionPhoto to version 4.1.51 or later through the Galaxy Store or Samsung Security Maintenance Release
- Apply the December 2025 Samsung Mobile security patch to affected devices
- Restrict installation of untrusted applications on devices handling sensitive data
Patch Information
Samsung addressed CVE-2025-58482 in Samsung MotionPhoto version 4.1.51. Patch details are available in the Samsung Security Update for December 2025.
Workarounds
- Block sideloading of applications by disabling installation from unknown sources
- Enforce mobile device management policies that limit which apps can be installed on corporate devices
- Educate users to avoid granting runtime permissions or interaction prompts to untrusted applications
# Configuration example - verify MotionPhoto version via adb
adb shell dumpsys package com.samsung.android.motionphoto.viewer | grep versionName
