VAR-202407-1619
Vulnerability from variot - Updated: 2025-08-15 23:17Tenda AX12 v1.0 v22.03.01.46 contains a stack overflow in the deviceList parameter of the sub_42E410 function. Shenzhen Tenda Technology Co.,Ltd. of AX12 A stack-based buffer overflow vulnerability exists in the firmware.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The Tenda AX12 is a dual-band Gigabit Wi-Fi 6 wireless router designed for home users. It supports dual-band concurrent transmission and achieves speeds of up to 2976 Mbps.
The Tenda AX12 suffers from a buffer overflow vulnerability caused by a bounds error when processing untrusted input in the deviceList parameter of the sub_42E410 function. An attacker could exploit this vulnerability to cause a denial of service
