Virtual machine escape vulnerability
An attacker who controls one guest virtual machine on a shared host at Tellis Cloud exploits a hypervisor flaw to run code on the host and access other tenants' VMs. What is this called?
- A.Resource reuse
- B.Jailbreaking
- C.Sideloading
- D.VM escape
Show answer and explanation
Correct answer: D. VM escape
Why: VM escape occurs when code inside a guest breaks out of its isolation to interact with the hypervisor or host, putting every VM on that host at risk. Resource reuse concerns leftover data in reassigned memory or storage. Sideloading and jailbreaking are mobile device risks.
