Memory corruption via oversized QosList value
Published Sep 10, 2025 · Updated Sep 10, 2025
Buffer overflow in Tenda F3 firmware beginning at 12.01.01.48_multi allows remote attackers to corrupt memory through a crafted QosList value. The goform/setQoS handler accepts an oversized QosList value and writes beyond a memory buffer; the copy primitive and buffer layout are undisclosed. Network access to the handler is required; exploitation is unauthenticated and requires no user interaction, but attack complexity is high.
