CVE-2022-48388

Local privilege escalation via unchecked powerEx requests

Published May 9, 2023 · Updated Jan 28, 2025

Missing authorization in the powerEx service on UNISOC chipsets with Android 10 through Android 13 allows local users to escalate privileges. The service fails to perform a required permission check before privileged processing; UNISOC has not disclosed the specific handler or operation. Exploitation is local, requires an already highly privileged caller, and needs no user interaction or additional execution privileges.
