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.
