A missing validation of the "int_ctl" VMCB field allows a malicious L1 guest to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. The L2 guest is able to write to a limited but still relatively large subset of the host physical memory, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape (CVE-2021-3653).
