CVE-2022-47344

Service interruption via unchecked array index

Published Feb 6, 2023 · Updated Mar 26, 2025

Array index underflow in UNISOC engineermode services on affected Android 10 and 11 chipsets allows local users to interrupt the service. The service accepts an array index without the permission check needed to prevent an underflow, but UNISOC has not disclosed the specific interface or function. Local access is required; exploitation interrupts engineermode services, with no published confidentiality or integrity impact.
