CVE-2023-42726

Local service crash via unchecked buffer read

Published Dec 4, 2023 · Updated May 29, 2025

Out-of-bounds read in UNISOC TeleService on Android 11 allows local users with System privileges to crash the service. TeleService omits a bounds check before reading an input, but UNISOC has not disclosed the affected function, input field, or exact read operation. Exploitation requires local System-level execution on a device using an affected chipset; the documented consequence is a service crash.
