Google Cloud Warns Three AMD Turin CPU Flaws Could Leak Data Across Processes in VMs

Google Cloud warned that three AMD Turin CPU flaws could leak data across processes in VMs. Google has applied mitigations against attacks between VMs and between VMs and the host, but inside a VM, an attacker with code on the same core could infer data from other processes or the kernel. A guest OS patch and stop-and-start are required.
