CVE-2025-48611
📋 TL;DR
This vulnerability in Android's DeviceId component allows local privilege escalation without user interaction due to a missing bounds check in persistence logic. It affects Android devices, particularly Google Pixel phones, enabling attackers to gain elevated system privileges from a standard user context.
💻 Affected Systems
- Google Pixel phones
- Android devices with similar DeviceId implementation
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attackers to install persistent malware, access all user data, bypass security controls, and potentially use the device as a foothold for network attacks.
Likely Case
Local privilege escalation allowing attackers to gain system-level access, install malicious apps, access sensitive data, and modify system settings.
If Mitigated
Limited impact if devices are fully patched, have strict app installation policies, and use security monitoring to detect privilege escalation attempts.
🎯 Exploit Status
No user interaction needed but requires local access; likely requires crafting specific DeviceId operations to trigger the bounds check issue.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: March 2026 Android security update
Vendor Advisory: https://source.android.com/docs/security/bulletin/pixel/2026/2026-03-01
Restart Required: Yes
Instructions:

🔧 Temporary Workarounds
Restrict app installations
androidOnly allow app installations from trusted sources like Google Play Store to reduce risk of malicious apps exploiting this vulnerability.
Enable Google Play Protect
androidEnsure Google Play Protect is active to detect and block potentially harmful apps.
🧯 If You Can't Patch
- Isolate affected devices from sensitive networks and data
- Implement strict app installation policies and monitor for suspicious privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level in Settings > About phone > Android version. If patch level is earlier than March 2026, device is vulnerable.Check Version:
Settings > About phone > Android version > Security patch levelVerify Fix Applied:
Verify Android security patch level shows 'March 5, 2026' or later in Settings > About phone > Android version.📡 Detection & Monitoring
Log Indicators:
