HighCVSS 7.8/10Last modified Jun 17, 2026

Description

On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process insecurely extracts the fields from the "shard" table of its SQLite database, leading to a buffer overflow on the stack. The strcpy call overflows the destination buffer, which has a size of 128 bytes. An attacker can send an arbitrarily long "secretKey" value in order to exploit this vulnerability.
