Vulnerability from github – Published: 2022-08-06 00:00 – Updated: 2022-08-09 00:00

Details

A stack-based buffer overflow vulnerability exists in the confsrv set_mf_rule functionality of TCL LinkHub Mesh Wifi MS1G_00_01.00_14. A specially-crafted network packet can lead to stack-based buffer overflow. An attacker can send a malicious packet to trigger this vulnerability.This vulnerability leverages the ethAddr field within the protobuf message to cause a buffer overflow.

Severity

9.8 (Critical)
