CVE-2023-42733

Local information disclosure via missing permission check

Published Dec 4, 2023 · Updated Aug 2, 2024

Missing authorization in UNISOC telephony service on affected chipsets allows local users to read sensitive information. UNISOC attributes the disclosure to a missing permission check but has not published the checked operation, service interface, or exposed data. An unprivileged local process on a device using a listed chipset can obtain information without user interaction; integrity and availability are unaffected.
