CVE-2023-48354

Local information disclosure via telephone-service input validation

Published Jan 18, 2024 · Updated Jun 20, 2025

Information disclosure in UNISOC telephone service on SC7731E and related chipsets with Android 11–13 allows local users to read data. The service improperly validates an unspecified local input, but UNISOC has not published the affected function, input field, or data exposed. Local reachability is required; vendor scoring treats exploitation as requiring no privileges or user interaction, and the reported consequence is confidentiality loss only.
