More than you might think - the following is from a NYT piece on the Meltdown flaw in many Intel and other CPUs (mind you, there's no evidence of this flaw yet being exploited in the wild):
"To take advantage of Meltdown, hackers could rent space on a cloud service, just like any other business customer. Once they were on the service, the flaw would allow them to grab information like passwords from other customers.
That is a major threat to the way cloud-computing systems operate. Cloud services often share machines among many customers — and it is uncommon for, say, a single server to be dedicated to a single customer. Though security tools and protocols are intended to separate customers’ data, the recently discovered chip flaws would allow bad actors to circumvent these protections."
