CVE-2022-48450

Local service interruption via unchecked parameters

Published Jul 12, 2023 · Updated Aug 3, 2024

Denial of service in UNISOC's Bluetooth service on Android 10, 11, and 12 allows local users to interrupt service via unchecked parameters. UNISOC attributes the failure to a missing parameter check but does not identify the affected function, parameter, or failure path. Exploitation requires local access with System execution privileges, and the disclosed consequence is a Bluetooth-service interruption.
