CVE-2022-48458

Unprivileged local system crash via unvalidated input

Published Nov 1, 2023 · Updated Sep 5, 2024

Improper input validation in UNISOC TeleService on Android 11 and 12 allows local users to crash the system through crafted input. UNISOC has not disclosed the TeleService entry point, input field, or validation operation that accepts the malformed data. No additional execution privileges or user interaction are required, and the documented consequence is a system crash rather than data access or modification.
