CVE-2022-48391

Local service interruption via missing permission check

Published Jun 6, 2023 · Updated Jan 8, 2025

Improper handling in Unisoc telephony service on Android 10 through Android 12 allows local users to interrupt service. The service omits a permission check for an undisclosed local request, then mishandles the resulting exceptional condition and loses availability. Unisoc has not disclosed the request, function, or precise failure mode; access is local, requires no additional execution privileges, and causes only a service interruption.
