CVE-2025-20780
📋 TL;DR
This CVE describes a use-after-free memory corruption vulnerability in display components that could allow local privilege escalation. Attackers who already have System privilege can exploit this without user interaction to gain higher privileges. The vulnerability affects MediaTek devices with specific display drivers.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with kernel-level access, allowing attackers to install persistent malware, steal sensitive data, or disable security controls.
Likely Case
Local privilege escalation from System to kernel or higher privileges, enabling further lateral movement within the device.
If Mitigated
Limited impact if proper privilege separation and memory protection mechanisms are in place, though exploitation risk remains.
🎯 Exploit Status
Exploitation requires System privilege first, then triggers use-after-free in display components. No user interaction needed once initial access achieved.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Patch ID: ALPS10184061
Vendor Advisory: https://corp.mediatek.com/product-security-bulletin/January-2026
Restart Required: Yes
Instructions:
1. Check device manufacturer for firmware updates. 2. Apply MediaTek patch ALPS10184061. 3. Reboot device after patch installation. 4. Verify patch application through version checks.
🔧 Temporary Workarounds
Restrict System Privilege Access
androidLimit which applications and users can obtain System privilege to reduce attack surface.
Disable Unnecessary Display Features
androidDisable advanced display features that may trigger vulnerable code paths.
🧯 If You Can't Patch
- Implement strict application sandboxing to limit System privilege access
- Deploy endpoint detection and response (EDR) solutions to monitor for privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against MediaTek security bulletin; examine display driver versions for pre-patch components.Check Version:
adb shell getprop ro.build.fingerprint (for Android devices)Verify Fix Applied:
Verify patch ALPS10184061 is applied through device firmware version checks and security patch level.📡 Detection & Monitoring
