Critical 16-Year-Old UEFI Flaw Can Run Code Before Secure Boot on Network-Booting Servers

Why am I seeing this Ranked on source trust — Feedburner
It ranks mainly on source trust: Feedburner is the most reliable outlet we track on this subject, and is the only one on the story so far.
Single-sourced. No second organisation has confirmed it yet.
Link-outLink-out, because only one organisation carries it and no first-party source is on it and the subject could not be identified from the text. Link-out means we point at the publisher and say nothing of our own.
| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|
| Corroboration | 0.35 | 0.39 | +0.135 37% | 1 independent org on the story. Tier-3 aggregators never corroborate — they can show something is circulating, never that it is true. |
| Source trustleads | 0.25 | 0.65 | +0.163 45% | Feedburner is the highest-trust source on this story. Trust is taken from the best source, not averaged. |
| Pickup rate | 0.20 | 0.00 | +0.000 0% | One counted organisation, so there is no spread to measure — nothing has picked this up to set a rate. |
| Freshness | 0.20 | 0.33 | +0.066 18% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.

What happened
A critical 16-year-old flaw in EDK II, the open-source code that most hardware makers use to build UEFI firmware, can allow an attacker to run code on a machine before its operating system loads, but only while the machine is booting over the network. UEFI firmware is the software that runs first when a computer is switched on, before the operating system.
