CVE-2022-38687

Local messaging-service interruption via missing permission check

Published Oct 14, 2022 · Updated May 15, 2025

Uncontrolled resource consumption in Unisoc messaging service on Android 10 through Android 12 allows local users to interrupt the service. An exposed messaging-service operation fails to perform a required permission check before consuming resources, but Unisoc has not disclosed the operation or resource involved. Exploitation requires local access and can deny messaging availability; the vendor assessment requires user interaction and no additional execution privileges.
