KVM_REQ_GET_NESTED_STATE_PAGES is cleared on VM-Exit\n\nAlways check and clear KVM_REQ_GET_NESTED_STATE_PAGES when emulating a\nnested VM-Exit to ensure the request is cleared, even when KVM was built\nwith CONFIG_KVM_HYPERV=n, as KVM subtly relies on the \"check\" to clear\nthe flag and thus avoid double-mapping the vmcs12 pages, e.g. if KVM\nmanages to bail from VM-Enter without processing the request, and then\nemulates VMLAUNCH or VMRESUME.","state":0,"publishedAt":"2026-09-16T10:32:22.202+00:00","modifiedAt":"2026-10-19T08:55:05.944+00:00","affected":[{"ecosystem":"Vendor
