CVE-2026-75619

Device reboot via RTSP length overflow

Published Aug 19, 2026 · Updated Aug 19, 2026

Heap-based buffer overflow in the RTSP service in TP-Link Tapo C100/C101 v5 allows remote authenticated users to reboot the device via crafted RTSP frame data. The RTSP service accepts oversized attacker-controlled length values and uses them for heap writes, causing out-of-bounds memory corruption in RTSP frame handling. Reachability is limited to attackers on the same local network with valid RTSP access, and the published impact is a temporary service interrupt through RTSP service crash and device reboot.
