CVE-2022-41480Network attack vector

Unauthenticated service interruption via request buffer overflow

Published Oct 13, 2022 · Updated May 15, 2025

Buffer overflow in Tenda AC6 V2.0 firmware 15.03.06.51 allows remote attackers to interrupt service via a crafted request. Function 0x475dc mishandles attacker-controlled request data by overrunning a buffer, although the published report does not identify the parameter or copy operation. No authentication or user interaction is required; the record limits impact to availability but does not specify whether interruption occurs by hang, crash, or reboot.
