CVE-2025-20775

Local privilege escalation via display use-after-free

Published Dec 2, 2025 · Updated Feb 26, 2026

Use-after-free memory corruption in MediaTek display components on Android 14.0, 15.0, and 16.0 allows local users to elevate privileges. The display component accesses memory after release, but MediaTek has not disclosed the affected routine, object-lifetime error, or triggering input. Exploitation requires existing System privilege and no user interaction, and successful abuse escalates privileges locally with confidentiality, integrity, and availability consequences.
