CVE-2026-97631 doesn’t affect home and small office users, or any other users who boot their devices solely from disk drives. Instead, it applies only to organizations with machines that boot from local networks, or conceivably from Internet-connected resources.

Thank you ever so much for this comforting snippet. πŸ™

Don't tell me what I can't do at home!!

At my company this isn't the norm. Maybe kickstart data comes from the network but not the OS itself.

[–] NGC2346@sh.itjust.works 5 points 5 days ago

Certain companies restore images through the network and/or solely boot machines from the network depending on the field of work, and this affects them.

Curious to how this could affect pxe imaging

So I'm guessing this means the wake on lan "magic packet"??

[–] Nollij@sopuli.xyz 6 points 5 days ago

No, it's a vulnerability with PXE booting, AKA "boot to network". While most hardware has the capability (often used to load the device in the first place), I would question how many are set to use this on a routine basis.

This sounds like something scary in a lab, but nearly useless in the real world.

[–] WhyJiffie@sh.itjust.works 3 points 5 days ago

no, that just wakes the system up.

this is about when the UEFI is configured to boot from network, instead of booting the operating system installed to a local disk.
