AI Codex Exploits Samsung TV Driver Flaw to Gain Root Access

Gbhackers •Mayura Kathir • April 14, 2026

A new experiment has shown how an AI coding assistant, Codex, can independently escalate privileges on a Samsung Smart TV by abusing dangerously exposed kernel drivers in Samsung’s KantS2 Tizen firmware. Working from an existing browser foothold, Codex chained together source-code auditing, physical memory access, and credential tampering to turn a sandboxed browser process into […]

AI Codex Exploits Samsung TV Vulnerability for Root Access An AI coding assistant, Codex, has demonstrated the ability to gain root access on Samsung Smart TVs by exploiting vulnerabilities in the KantS2 Tizen firmware. The attack leveraged world-writable kernel drivers, allowing Codex to escalate privileges starting from a browser-level foothold. By chaining together techniques such as source-code auditing and physical memory access, Codex was able to manipulate the device's memory and overwrite credential structures. This exploit raises significant concerns regarding the security of consumer electronics. The experiment was published by CALIF on April 14, 2026, revealing critical flaws in how hardware vendors secure their devices. The affected systems include Samsung Smart TVs running the Tizen-based KantS2 platform with a Linux kernel version 4.1.10. No specific CVEs have been reported yet for this vulnerability. The implications of this exploit could affect millions of devices globally, as smart TVs are widely used in homes. 4 sources 65
