CVE-2026-51606: n/a
An improper input handling vulnerability exists in the RTSP service of Tenda CP3 V3.0 (firmware V31.1.9.91). When the device receives an RTSP request with an oversized field value in the request-line URL or header fields, it abruptly terminates the TCP connection with a reset (RST) packet instead of returning a proper RFC 2326-compliant error response. This affects multiple RTSP request types and may disrupt normal RTSP communication.
AI Analysis
Technical Summary
CVE-2026-51606 describes a vulnerability in the RTSP service of Tenda CP3 V3.0 devices running firmware version V31.1.9.91. The issue arises from improper input handling of oversized field values in RTSP requests. Instead of responding with a compliant error message as per RFC 2326, the device forcibly closes the TCP connection with a reset packet. This behavior impacts the request-line URL field and header fields across multiple RTSP request types, potentially causing denial of service or disruption of RTSP sessions.
Potential Impact
The vulnerability causes the device to abruptly terminate RTSP TCP connections when oversized field values are received, disrupting RTSP communications. There is no indication of code execution or data leakage. The primary impact is denial of service or interruption of RTSP streaming sessions due to connection resets.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is provided at this time.
