Summary
An exploitable stack-based buffer overflow vulnerability exists in the retrieval of a database field in video-core's HTTP server of Samsung SmartThings Hub. The video-core process insecurely extracts the shard.videoHostURL field from its SQLite database, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.
Exploit prediction
0.41% chance of exploitation in the next 30 days, higher than 35% of all scored CVEs (FIRST EPSS, 2026-11-09).
