CVE-2026-12935 Vulnerability Summary

CVE-2026-12935: 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.

Assessing the Risk of CVE-2026-12935

Access Complexity Graph

The exploitability of CVE-2026-12935 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-12935

No exploitability data is available for CVE-2026-12935.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
