Vulnerability from fkie_nvd - Published: 2026-06-24 19:17 - Updated: 2026-06-29 16:17
Severity
6.5 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A denial-of-service (DoS) vulnerability has been identified in Tapo C200 v3 in the network packet handling logic due to improper handling of IPv4 fragmented packets.  An unauthenticated adjacent attacker can send crafted packets to cause excessive resource consumption, leading to instability of the device.Successful exploitation can remotely trigger a temporary denial-of-service condition, causing the camera to become unresponsive and resulting in intermittent loss of video monitoring and recording.
