Local privilege escalation via missing permission check
Published Dec 4, 2023 · Updated Aug 28, 2024
Missing authorization in the UNISOC telocom service on Android 11, 12, and 13 allows local users to escalate privileges. The service omits a required permission check, although UNISOC has not disclosed the checked operation, request, or code locus. No existing execution privileges or user interaction is required; exploitation crosses a security boundary and can alter data or interrupt service.
