Whither Fuchsia? Will the new OS be Google's way to avoid sharing Linux code?

If Google decides to use its new operating system Fuchsia will it lead to the company abandoning Linux - the kernel is used in Android - and lead to what one security professional is claiming will be "withdrawal of resources, investment, and Linux's largest userbase"? If this happens at the same time as the rise of Fuchsia is it certain it "will have a devastating effect"?

  • Security Researchers Attacked Google’s Mysterious Fuchsia OS: Here’s What They Found

    A couple of things that Computer Business Review has widely covered are important context for the security probe. (These won’t be much surprise to Fuchsia’s followers of the past two years.)

    i.e. Fuschsia OS is based on a tiny custom kernel from Google called Zircon which has some elements written in C++, some in Rust. Device drivers run in what’s called “user mode” or “user land”, meaning they’re not given fully elevated privileges. This means they can be isolated better.

    In user land, everything that a driver does has to go via the kernel first before hitting the actually computer’s resources. As Quark Labs found, this is a tidy way of reducing attack surface. But with some sustained attention, its researchers managed to get what they wanted: “We are able to gain kernel code execution from a regular userland process.”
