From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yes, enhanced security is pretty much the entire pitch of Rust. There wouldn't be any reason for it to result in performance enhancements, though.

It just depends on how isolated that part of the kernel is. Unsafe code should be done only in interop, and so it still theoretically has a memory safety benefit over C in that sense.
In terms of how much interop code needs to be written for Rust at this point is another discussion though.
