CVE-2026-89931 | BDVDB-2026-375211 Detail

Description#

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.
