System-privileged escalation via incorrect GNSS bounds check
Published Oct 14, 2025 · Updated Oct 14, 2025
Out-of-bounds write in MediaTek GNSS Driver on Android 14.0 and 15.0 allows local users with System privilege to escalate privileges. The vendor identifies an incorrect bounds check in the GNSS driver but has not disclosed the affected function, input, or write operation. Exploitation requires existing System privilege and no user interaction; the resulting memory corruption grants higher local privileges.
