CVE-2025-48580 Overview
CVE-2025-48580 is a local privilege escalation vulnerability in the Android platform. The flaw resides in the connectInternal method of MediaBrowser.java within the Android frameworks/base component. A logic error allows an application to access while in use permissions while running in the background. Exploitation requires no user interaction and no additional execution privileges beyond those already granted to a local app. Google addressed the issue in the December 2025 Android Security Bulletin.
Critical Impact
A local app can obtain foreground-only permissions while backgrounded, enabling access to sensitive resources such as microphone, camera, or location without user awareness.
Affected Products
- Google Android 13.0
- Google Android 14.0
- Google Android 15.0 and Android 16.0

Technical Details for CVE-2025-48580
Vulnerability Analysis
The vulnerability is a logic error in MediaBrowser.connectInternal(), a framework API that establishes a connection between a client app and a MediaBrowserService. Android enforces while in use (foreground-only) runtime permissions such as ACCESS_FINE_LOCATION, CAMERA, and RECORD_AUDIO by binding permission grants to the app's process state. The affected code path fails to correctly validate the caller's foreground state during the connect sequence.
As a result, a background app can invoke media browser connect logic and reach code paths that treat the app as if it held the foreground-scoped permission. This produces local privilege escalation without any UI prompt or user confirmation. The advisory classifies the issue under [NVD-CWE-noinfo] because Google did not publish a precise CWE mapping.
Root Cause
The root cause is improper enforcement of process-state checks inside connectInternal. The method extends effective permission scope beyond the app's actual foreground lifecycle. The upstream fix in commit eb19b27ed8abe9070df9fb85bc9693c8d4ba321b tightens this validation.
Attack Vector
Exploitation requires a locally installed application on the device. The malicious app initiates a media browser connection sequence while backgrounded and leverages the logic flaw to exercise APIs guarded by while in use permissions. See the Android Security Bulletin December 2025 and the Android Source Code Update for the reference fix.
Detection Methods for CVE-2025-48580
Indicators of Compromise
- Installed applications that bind to MediaBrowserService yet declare no legitimate media playback functionality.
- Background processes accessing LocationManager, CameraManager, or AudioRecord APIs shortly after establishing a media browser connection.
- Anomalous foreground-only permission usage attributed to apps that lack a visible activity.
Detection Strategies
- Review AppOps logs and privacy dashboard entries for background access to camera, microphone, and location on Android 13 through 16 devices.
- Inspect installed APKs for calls to MediaBrowser.connect() combined with declarations of ACCESS_BACKGROUND_LOCATION, CAMERA, or RECORD_AUDIO permissions.
- Correlate mobile telemetry with MDM inventory data to identify unpatched devices below the 2025-12-01 security patch level.
Monitoring Recommendations
- Enforce a minimum Android security patch level of 2025-12-01 through mobile device management compliance policies.
- Monitor for privacy indicator events (green camera/microphone dot) triggered while no app is in the foreground.
- Alert on newly sideloaded applications that request media browser bindings on managed devices.
How to Mitigate CVE-2025-48580
Immediate Actions Required
- Apply the December 2025 Android security update (patch level 2025-12-01 or later) on all Android 13, 14, 15, and 16 devices.
- Block device enrollment or corporate resource access for endpoints below the required patch level via MDM conditional access.
- Audit installed apps and remove any untrusted applications that request foreground-only sensitive permissions.
Patch Information
Google merged the fix into AOSP under commit eb19b27ed8abe9070df9fb85bc9693c8d4ba321b in platform/frameworks/base. The patch is distributed through OEM security updates aligned to the Android Security Bulletin December 2025. Device vendors ship the fix at security patch level 2025-12-01 or later.
Workarounds
- Revoke while in use permissions (location, camera, microphone) from non-essential apps until the patch is applied.
- Restrict app installation sources to Google Play and enforce Google Play Protect scanning.
- Use work profile separation to limit exposure of corporate data on personally owned devices pending vendor patch delivery.
# Verify Android security patch level on a managed device
adb shell getprop ro.build.version.security_patch
# Expected output: 2025-12-01 or later
