- digikata 9y agoSo there's a bit of an unknown if AMD's most recent generation of processor has the Spectre vulnerability?
- sbx320 9y agoFrom the Spectre paper: > We have also verified the attack’s applicability to AMD Ryzen CPUs.
- lettergram 9y agoWe know that the scariest attack "meltdown", cannot be reproduced on AMD or ARM chips at all[1]. The second attack "Spectre" is also greatly mitigated due the neural network predicting pathways for the application. Thus it's unlikely/less-likely that you'll be able to access other locations in memory[2]. However, it's definitely possible.

- RandomBK 9y agoHas anyone tried the Spectre PoC in the paper on ThreadRipper? I can confirm it works on my i7-7700K.
- AnssiH 9y agoARM advisory [1] does state that Cortex-A75 is vulnerable to variant 3 (Meltdown). [1] https://developer.arm.com/support/security-update https://developer.arm.com/support/security-update
