Google Cloud issues security advisory on AMD Turin CPU Transient Scheduler Attacks
What happened.Google Cloud published a security bulletin detailing three processor side-channel vulnerabilities affecting virtual machines running on fifth-generation AMD EPYC Turin processors.
Why it matters.Virtual machine isolation is the core boundary of multi-tenant cloud hosting. When speculative execution flaws allow unprivileged processes to infer kernel memory, application data faces exposure. Cloud infrastructure teams using AMD Turin instances must schedule maintenance windows to complete full stop-start cycles immediately.
