What it is

In the Linux kernel, the following vulnerability has been resolved:

KVM: nVMX: Ensure KVM_REQ_GET_NESTED_STATE_PAGES is cleared on VM-Exit

Always check and clear KVM_REQ_GET_NESTED_STATE_PAGES when emulating a

nested VM-Exit to ensure the request is cleared, even when KVM was built

with CONFIG_KVM_HYPERV=n, as KVM subtly relies on the "check" to clear

the flag and thus avoid double-mapping the vmcs12 pages, e.g. if KVM

manages to bail from VM-Enter without processing the request, and then

emulates VMLAUNCH or VMRESUME.
