CVE-2023-42723

Local service interruption via unchecked buffer read

Published Dec 4, 2023 · Updated Aug 2, 2024

Out-of-bounds read in the Unisoc Android 11 camera service allows local users to interrupt the service via unspecified vectors. The service reads beyond an intended buffer because it fails to check an unspecified input boundary; Unisoc has not identified the affected function or input field. Local access is required, but no execution privileges or user interaction are needed, and the reported consequence is limited to denial of service.
