CVE-2022-24018

Memory corruption via unchecked GetValue copy

Published Aug 5, 2022 · Updated Apr 15, 2025

Buffer overflow in multiWAN on TCL LinkHub Mesh Wi-Fi MS1G_00_01.00_14 allows remote attackers to corrupt memory via configuration values. GetValue copies flash-configuration data into caller-provided destinations without accounting for destination size, affecting 127 calls in multiWAN. Network proximity and access to the protobuf management service are required; the public report establishes memory corruption but no narrower per-call consequence.
