CVE-2025-22429: Google Android Privilege Escalation Flaw

CVE-2025-22429 Overview

CVE-2025-22429 is a code execution vulnerability affecting Google Android versions 13, 14, and 15. The flaw stems from a logic error present in multiple code locations within the Android platform. Attackers can leverage the weakness to execute arbitrary code and achieve local privilege escalation without requiring additional execution privileges. Exploitation does not require user interaction, which expands the attack surface considerably.

Google addressed the issue in the Android Security Bulletin published on April 1, 2025. The vulnerability is tracked under CWE-693: Protection Mechanism Failure.

Critical Impact

Attackers can execute arbitrary code on affected Android devices with no user interaction, leading to local privilege escalation across Android 13, 14, and 15.

Affected Products

• Google Android 13
• Google Android 14
• Google Android 15

Technical Details for CVE-2025-22429

Vulnerability Analysis

The vulnerability resides in multiple locations within the Android platform code, specifically within the frameworks/base component. According to the Android source commit, the defect is a logic error that fails to enforce intended protection mechanisms before allowing code paths that lead to arbitrary code execution.

Because the flaw appears in more than one location, a single patch must address each affected code path. The condition can be triggered without user interaction, which removes a common barrier to reliable exploitation on mobile platforms.

The EPSS score is approximately 0.07%, indicating low observed exploitation activity at the time of publication. However, the absence of authentication and user interaction requirements raises the practical risk for unpatched devices.

Root Cause

The root cause is a logic error mapped to CWE-693 (Protection Mechanism Failure). The affected code paths do not correctly validate state or permissions before executing privileged operations. As a result, an attacker reaching the vulnerable code can bypass the intended security boundary and execute code with elevated privileges. The fix is published in the Android commit ece83fb425b1e912a036e9985b710910e2e3ca37.

Attack Vector

The NVD entry classifies the network attack vector with low complexity and no privileges required. The advisory description indicates local privilege escalation as the resulting impact, meaning a remote trigger can lead to elevated execution on the target device. No public proof-of-concept code is currently available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

No verified exploitation code is available. Refer to the Android source commit for the patch-level technical details.

Detection Methods for CVE-2025-22429

Indicators of Compromise

• Unexpected processes or services running with elevated privileges on Android 13, 14, or 15 endpoints
• Application crashes or unusual stack traces originating from Android frameworks/base system services
• Outbound network connections from system processes to untrusted hosts following receipt of unsolicited input

Detection Strategies

• Inventory mobile devices and compare installed Android security patch levels against the April 2025 bulletin baseline
• Monitor mobile device management (MDM) telemetry for devices reporting patch levels older than 2025-04-01
• Correlate device logs with enterprise SIEM platforms to flag privilege escalation patterns or anomalous system service behavior

Monitoring Recommendations

• Enroll Android endpoints in an MDM or Unified Endpoint Management (UEM) solution that reports security patch level
• Forward mobile threat defense (MTD) telemetry into a centralized data lake for behavioral analysis
• Alert on devices that fail to apply the April 2025 or later Android security patch within enterprise compliance windows

How to Mitigate CVE-2025-22429

Immediate Actions Required

• Apply the April 2025 Android security patch level (2025-04-01) or later on all Android 13, 14, and 15 devices
• Identify devices that cannot receive the patch from their carrier or OEM and restrict their access to sensitive enterprise resources
• Validate patch deployment through MDM compliance reports and remediate non-compliant devices

Patch Information

Google released the fix in the Android Security Bulletin dated April 1, 2025. The corresponding source change is published in commit ece83fb425b1e912a036e9985b710910e2e3ca37 in the platform/frameworks/base repository. OEMs and carriers integrate the patch into their device-specific builds before delivering it to end users.

Workarounds

• No vendor-provided workaround exists; patching is the only supported remediation
• Limit installation of untrusted applications and disable sideloading on managed devices until patches are confirmed
• Restrict access to corporate resources from devices reporting a patch level earlier than 2025-04-01 using conditional access policies

# Verify the Android security patch level on a device via ADB
adb shell getprop ro.build.version.security_patch
# Expected output for remediated devices: 2025-04-01 or later
