VM Escape

Term: VM Escape / Container Escape

Definition: An attack where code running inside a VM or Container breaks out of its isolation and gains control of the host or other guests.

Context/Example: A malicious program inside a Container exploits a kernel bug to get root on the host Linux system—this is the “holy grail” for Virtualization attackers.
