The TL-WR940N v6 router contains a vulnerability in its RTSP connection tracking module that can lead to a stack-based buffer overflow. The issue occurs when a LAN client initiates a connection to a malicious RTSP server controlled by an attacker. A specially crafted RTSP message may trigger improper memory handling within the kernel module

Successful exploitation of this vulnerability may result in a denial-of-service (DoS) condition or allow remote code execution (RCE), potentially leading to full compromise of the device. This vulnerability can be exploited by an unauthenticated attacker under the device's default configuration.
