Summary from the TLDR Dev newsletter

OpenAI's Codex successfully escalated privileges to gain root access on a Samsung Smart TV. Researchers provided Codex with an initial browser shell foothold and the TV's firmware source, tasking the AI with finding a vulnerability to achieve root. Codex identified a critical flaw in the `ntksys` kernel driver, which allowed it to map arbitrary physical memory into user space and overwrite the browser process's kernel credentials.
