What the hell is up with that comparison at the end?! Seems... overly verbose?

Most likely this is decompiled and not the way it was originally written.

Yep, and you can prompt something like "the function was a decompiled version, translate it into a readable version", if you don't like reading [probably] ghidra output.

The programmer probably wrote memcmp(pass, buf, 5) which compilers will often fold into an inlined loop, or a few comparisons if they know the 3rd arg.

The weird thing is it didn't emit a 32-bit load+compare for the first 4 bytes, this could probably be done with 2 comparsions. Idk. Maybe weird CPU with stricter alignment rules.

It's a fridge. Who knows what microcontroller CPU is there, and which toolchain they use.
