+We recommend that all developers upgrade to this v1.4 release, which

-AP Trampoline Is Accessible to Service VM
-   This vulnerability is triggered when validating the memory isolation between
-   VM and hypervisor. AP Trampoline code exists in LOW_RAM region in hypervisor but is
-   potentially accessible to service VM. This could be used by an attacker to mount DoS
-   attacks on the hypervisor if service VM is compromised.
