CVE-2026-51601

Tenda CP3 V3.0 firmware V31.1.9.91 contains a stack-based buffer overflow in the RTSP service. The device fails to validate the length of the clock= value in the Range header field when processing a PLAY request. An unauthenticated remote attacker who has completed a standard RTSP session handshake can send a PLAY request with an excessively long clock= value to cause the RTSP service to crash.
