CVE-2022-48376

Local dialer denial of service via missing authorization

Published May 9, 2023 · Updated Jan 28, 2025

Missing authorization in UNISOC chipset firmware for Android 10 through Android 13 allows local users to interrupt dialer service. The dialer service performs an unspecified operation without checking the caller's required permission; UNISOC has not disclosed the affected entry point. A local caller needs no additional execution privileges, and the reported consequence is denial of dialer availability rather than device-wide shutdown.
