Summary
An exploitable stack-based buffer overflow vulnerability exists in the samsungWifiScan callback notification of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17. The video-core process incorrectly handles the answer received from a smart camera, leading to a buffer overflow on the stack. An attacker can send a series of HTTP requests to trigger this vulnerability.
Exploit prediction
2.01% chance of exploitation in the next 30 days, higher than 81% of all scored CVEs (FIRST EPSS, 2026-11-09).
