CVE-2025-0078

8.8 HIGH

📋 TL;DR

This CVE describes a logic error in Android's SELinux implementation that allows local privilege escalation without user interaction. Attackers can bypass SELinux restrictions to gain elevated privileges on affected devices. This affects Android devices running vulnerable versions of the operating system.

💻 Affected Systems

Products:
  • Android
Versions: Android versions prior to March 2025 security patch
Operating Systems: Android
Default Config Vulnerable: ⚠️ Yes
Notes: Affects devices with SELinux enabled (default on modern Android). Requires attacker to have local access to device.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device compromise allowing attackers to execute arbitrary code with kernel privileges, access all user data, and potentially persist across reboots.

🟠

Likely Case

Local attackers gain root access to the device, enabling data theft, surveillance capabilities, and installation of persistent malware.

🟢

If Mitigated

With proper SELinux policies and device hardening, impact is limited to specific contexts where the logic error can be triggered.

🌐 Internet-Facing: LOW (requires local access to device)
🏢 Internal Only: HIGH (local attackers can exploit without network access)

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires local access but no user interaction. Exploit likely requires understanding of SELinux internals and Android framework.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: March 2025 Android Security Patch

Vendor Advisory: https://source.android.com/security/bulletin/2025-03-01

Restart Required: Yes

Instructions:

1. Apply March 2025 Android Security Patch via OTA update or manual flash. 2. Verify patch installation in Settings > About phone > Android version. 3. Reboot device after patch installation.

🔧 Temporary Workarounds

Restrict local access

all

Limit physical and remote local access to devices through device management policies

Enhanced monitoring

linux

Monitor for unusual privilege escalation attempts and SELinux policy violations

adb logcat | grep -i 'avc:.*denied'
adb shell dmesg | grep -i selinux

🧯 If You Can't Patch

  • Implement strict physical security controls for devices
  • Use mobile device management (MDM) to enforce security policies and monitor for suspicious activity

🔍 How to Verify

Check if Vulnerable:

Check Android security patch level in Settings > About phone > Android version. If patch level is earlier than March 2025, device is vulnerable.

Check Version:

adb shell getprop ro.build.version.security_patch

Verify Fix Applied:

Verify security patch level shows 'March 1, 2025' or later in Settings > About phone > Android version.

📡 Detection & Monitoring

Log Indicators:

  • SELinux AVC denials for unexpected contexts
  • Unexpected privilege escalation in system logs
  • Processes running with unexpected SELinux contexts

Network Indicators:

  • Not applicable - local exploit only

SIEM Query:

source="android_logs" AND ("avc: denied" OR "selinux" OR "privilege escalation")
