Device crash via undisclosed handler buffer overflow
Published Jun 30, 2026 · Updated Jun 30, 2026
Buffer overflow in the gohead sub_472f08 handler in UTT nv518G firmware nv518GV3v3.2.7-210919-161313 allows remote attackers to crash the device. Public technical material names the handler but does not identify the affected buffer, unsafe operation, or attacker-controlled input. Network reachability to the handler is required, and the published consequence is limited to a device crash and service interruption.
