CVE-2025-68970: Huawei EMUI Auth Bypass Vulnerability

CVE-2025-68970 Overview

CVE-2025-68970 is a permission verification bypass vulnerability in the media library module of Huawei EMUI and HarmonyOS. The flaw allows a local, low-privileged actor to access media resources that should be gated by permission checks. Successful exploitation may affect the confidentiality of media data managed by the device.

Huawei disclosed the issue in its January 2026 consumer security bulletin. The vulnerability is categorized under CWE-20: Improper Input Validation and requires local access with low privileges and no user interaction.

Critical Impact

A local attacker with low privileges can bypass media library permission checks to read sensitive media content stored on affected Huawei EMUI and HarmonyOS devices.

Affected Products

• Huawei EMUI versions 13.0.0, 14.0.0, 14.2.0, and 15.0.0
• Huawei HarmonyOS versions 3.0.0, 3.1.0, 4.0.0, 4.2.0, 4.3.0, and 4.3.1
• Huawei consumer devices, vision products, and wearables running the affected operating system versions

Technical Details for CVE-2025-68970

Vulnerability Analysis

The vulnerability resides in the media library module of Huawei EMUI and HarmonyOS. The module is responsible for indexing, retrieving, and brokering access to media assets such as images, audio, and video on the device. A flaw in the permission verification logic allows requests to bypass the access controls that normally restrict media reads to authorized callers.

Because the attack vector is local and requires low privileges, an unprivileged application installed on the device is sufficient to trigger the condition. No user interaction is required, which means the bypass can occur silently in the background once the malicious application executes. The scope is unchanged and impact is limited to confidentiality, with no direct impact on integrity or availability.

Root Cause

The underlying weakness maps to CWE-20: Improper Input Validation. The media library module does not adequately validate the parameters or caller context of permission checks before returning media resources. As a result, the authorization layer can be circumvented by a local caller crafting a request that the module fails to evaluate correctly.

Attack Vector

Exploitation requires a local foothold on the device, such as a sideloaded or installed application that holds only basic runtime permissions. The malicious application interacts with the media library inter-process interface and submits requests that evade the permission verification routine. Huawei has not publicly released exploitation specifics, and no public proof-of-concept code is available. Technical details are available in the Huawei Security Bulletin.

Detection Methods for CVE-2025-68970

Indicators of Compromise

• Applications without granted media or storage permissions issuing repeated queries against the media library service.
• Unexpected enumeration of Images, Video, or Audio collections by background processes shortly after install.
• Anomalous reads of media URIs by applications that do not have a legitimate media-handling purpose.

Detection Strategies

• Audit installed applications and review which packages interact with the media library inter-process interfaces.
• Monitor mobile device management (MDM) telemetry for non-system applications attempting privileged content provider access on Huawei devices.
• Correlate application install events with subsequent media access patterns to identify newly installed apps that immediately query the media library.

Monitoring Recommendations

• Track OS build numbers across the Huawei fleet and flag devices still running EMUI 13.0.0–15.0.0 or HarmonyOS 3.0.0–4.3.1 without the January 2026 patch.
• Subscribe to the Huawei consumer security bulletins to track follow-up advisories.
• Review application permission usage reports for spikes in media access by low-trust applications.

How to Mitigate CVE-2025-68970

Immediate Actions Required

• Apply the January 2026 Huawei security update on all EMUI and HarmonyOS devices in scope.
• Remove untrusted or sideloaded applications, particularly those requesting broad inter-process access.
• Enforce installation of applications only from the vetted vendor app store via MDM policy.

Patch Information

Huawei addressed CVE-2025-68970 in the January 2026 security update cycle. Patch availability for specific device models is published in the Huawei Security Bulletin, the Huawei Vision Bulletin, and the Huawei Wearables Bulletin. Administrators should confirm the patched build for each device model and push updates through their device management platform.

Workarounds

• Restrict installation of third-party applications outside the official Huawei AppGallery until patches are deployed.
• Use MDM controls to limit which applications can request media or storage-related permissions on managed devices.
• Educate users to avoid installing applications from unknown sources and to review permission prompts carefully.
