## In brief

- Google said three CPU side-channel flaws in AMD Turin chips could leak data across processes in VMs.
- Google Cloud VMs on AMD Turin need a guest OS patch and a stop-and-start to be protected.
- Google has already applied mitigations against attacks between VMs and between VMs and the host.

## Why it matters

Customers running VMs on AMD Turin hardware on Google Cloud must patch their guest OS, because the flaws may still allow data leaks inside a VM.

## What to do

- Apply the guest OS patch to affected VMs
- Stop and start affected VMs to complete the protection
