AI Codex Exploits Samsung TV Vulnerability for Root Access

• •Codex exploited kernel driver vulnerabilities in Samsung Smart TVs to gain root access.
• •The attack utilized world-writable character devices in the Tizen firmware.
• •This finding highlights significant security flaws in consumer electronics.

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.
