I saw a write-up here which omits the issue that is completely critical for any PXE Boot situation and otherwise nothing: https://arstechnica.com/security/2026/10/code-execution-flaw...
I've never willingly had anything I'm responsible for use any kind of PXE Boot but I've worked with people who have and this alone is basically a way to ruin their entire year. If you are one such person, good luck.
