- bitwize 9y agoUnlikely, because the VM probably doesn't have fine-grained control over which system calls are made when, which is necessary for a Meltdown attack. VMs are, however, suscpetible to some forms of Spectre attack, allowing code within a VM to exfiltrate memory contents from other VMs, or from the host machine.
