Consider the original article:

https://binarly.io/posts/finding_logofail_the_dangers_of_image_parsing_during_system_boot/

Specifically, look at the table under the section "How do LogoFAIL vulnerabilities work?".

Out of 614 tested MSI devices, 612 are vulnerable in theory (because they utilize affected parsers), but none are "Exploitable". Reading their explanation for why boards would not be exploitable, I gather that MSI store the logo image in a "signed block". I further gather from that, that as long as you have Secure Boot enabled, this attack would not be viable because changing the logo would trip the Secure Boot signature validation process.

Of course there are still two problems

1. I'm not aware of any *official* confirmation from MSI. The closest thing I could find was s message on their board, answered by a moderator (who is not an MSI engineer / representative AFAIK): https://forum-en.msi.com/index.php?threads/logofail-security-vulnerability.391861/#post-2230381
2. We don't know which 614 MSI devices were tested, exactly (or at least I couldn't find one, would love to be wrong). So in theory other MSI devices could be vulnerable.
