Looks like AMD's ROM Armor feature was made public. This feature is direct result of our research. Hugo and myself discovered race condition in AMD's chipset. Rather than doing proper coordinated disclosure AMD marketed their fix it as a new feature. bit.ly/3qmvbcJ 🧵
It is similar to Intel's SpeedRacer vulnerability. When chipset receives SMI# signal it unlocks SPI controller but there is no guarantee all threads entered SMM. So we have a small time window to sneak commands directly to SPI BAR.
Since this vulnerability permanently exists in their hardware they disabled access to SPI controller from Ring0 and SMM and moved all SPI related operations to PSP for which Hugo found bunch of bypasses and credited in recent #PatchTuesday
