Local privilege escalation via display bounds omission
Published Dec 2, 2025 · Updated Feb 26, 2026
Out-of-bounds read in the MediaTek display component on affected Android 14.0, 15.0, and 16.0 chipsets allows local users to escalate privileges. The display component reads beyond an intended buffer because it omits a boundary check; MediaTek has not disclosed the affected function or input path. Exploitation requires existing System privilege and no user interaction; the record does not identify the resulting privilege level or exposed data.
