CVE-2022-48382

Local service interruption via unchecked buffer write

Published May 9, 2023 · Updated Jan 28, 2025

Out-of-bounds write in the UNISOC Android log service allows local users with System privileges to interrupt the service. The service writes beyond a buffer after failing to check the bounds of an unspecified input; UNISOC has not disclosed the function or field involved. Exploitation requires local access and System execution privileges; the documented consequence is service interruption without reported data disclosure or modification.
