Explanation

A VM escape attack is a critical vulnerability where malicious code running inside a virtual machine exploits a flaw in the hypervisor to break out of the isolated VM environment and gain access to the host OS or other VMs. Keeping the hypervisor fully patched closes known vulnerabilities that attackers could exploit to achieve this escape. Option A is incorrect because host OS vulnerabilities are addressed by patching the host OS, not the hypervisor. Option C (misconfigurations) is addressed through hardening, not patching. Option D (enabling features) is a benefit but not a security reason for mandatory patch policies.
