CVE-2022-48452

Local service interruption via missing permission check

Published Sep 4, 2023 · Updated Sep 30, 2024

Missing authorization in the IFAA service on UNISOC chipsets running Android 10 through Android 13 allows local users to interrupt service. The service omits a permission check before processing a local request, but UNISOC has not disclosed the request handler, input, or failure path. UNISOC reports no required privileges and limited integrity and availability effects, while NVD reports elevated privileges and an availability-only interruption.
