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

Google says cloud virtual machines on AMD Turin chips need a guest operating system patch and a stop-and-start to protect against three CPU side-channel flaws. Google has already applied mitigations against attacks between virtual machines and between VMs and the host. Inside a VM, the flaws may let an attacker with code on the same processor core infer data from other processes or the kernel.
