CVE-2025-20784

Local privilege escalation via uninitialized display data

Published Jan 6, 2026 · Updated Jan 6, 2026

Uninitialized data in MediaTek Display Driver on Android 14.0, 15.0, and 16.0 allows local users with System privilege to escalate privileges. The display component uses uninitialized data and corrupts memory; MediaTek does not disclose the variable, function, or operation involved. Exploitation requires existing System privilege and no user interaction, and successful corruption grants higher local privileges.
