AI Codex Exploits Samsung TV Driver Flaw to Gain Root Access

Researchers demonstrated an AI-assisted proof-of-concept privilege escalation on Samsung KantS2 Tizen smart TVs by abusing world-writable Novatek kernel drivers (ntksys, ntkhdma, ntkxdma). Using a physmap primitive to map physical memory and memfd-based in-memory execution to bypass unsigned-binary protections, the team located and overwrote browser process credentials to gain root, highlighting both a critical driver-design flaw and how AI can accelerate exploit development; the report recommends driver hardening, stricter device-node permissions, and reducing exposed kernel attack surface.
