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.

In short, the adversary requires elevated access to replace a file on the EFI partition. In this case, you should consider the machine compromised with or without this flaw.
You weren't hoping that Secure Boot saves your ass, were you?
Doesn't this mean that secure boot would save your ass? If you verify that the boot files are signed (secure boot) then you can't boot these modified files or am I missing something?
If I can replace a file in your EFI, how hard would it be to sign the same file.
Well, it rules out an evil maid attack and maybe jumping over a dual boot setup.
