Just about every Windows and Linux device vulnerable to new LogoFAIL firmware attack

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.

So I don't get it, I have my entire boot image in a signed EFI binary, the logo is in there as well. I don't think I'm susceptible to this, right? I don't think systemd-boot or the kernel reads an unsigned logo file anywhere. (Using secure boot)
This is way before reaching your bootloader. It's about the manufacturer logo that's displayed by UEFI while doing the whole hardware initialization.
That's.... Stored in the EFI partition or changeable in userspace?
(from the article)
Right, I know EFI images are stored in the EFI partition, but with secure boot, only signed images can be executed, so they'd need to steal someone's signing key to do this.
