System76 Reveals An Open Source PC Surprise For AMD Ryzen Fans
"We will be the only ones in the universe offering these processors with open source firmware"
#Intel and #AMD Hertzbleed CPU #Vulnerability Uses Boost Speed to Steal Crypto Keys
Intel and researchers from UT Austin, UIUC, and UW published papers today outlining the 'Hertzbleed' chip vulnerability that allows side-channel attacks that can steal secret AES cryptographic keys by observing the CPU's boost frequency/power mechanisms. Both Intel and AMD CPUs are impacted.
The vulnerability impacts all Intel processors and AMD Zen 2 and Zen 3, but it isn't clear if it will impact the upcoming Zen 4 Ryzen 7000.
