CVE-2023-52534Network attack vector

Remote service interruption via incorrect error handling

Published Apr 8, 2024 · Updated Nov 5, 2024

Improper exceptional-condition handling in UNISOC ngmm on T760, T770, T820, and S8000 chipsets allows remote attackers to interrupt service. Incorrect error handling in the modem component produces undefined behavior; UNISOC has not disclosed the responsible operation or input. Network reachability is required, no authentication or user interaction is needed, and the documented consequence is limited to service interruption.
