"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: x86: Re-pend GET_NESTED_STATE_PAGES if getting said pages fails\n\nRe-pend GET_NESTED_STATE_PAGES before exiting to userspace if getting the\nnested pages fails in the KVM_RUN path. If userspace re-runs the vCPU, and\nvmcs02 holds valid PFNs from the *previous* run of L2, then KVM could\nre-enter L2 with stale, unpinned PFNs mapped into e.g. the vAPIC page.\n\nNote, both SVM and VMX (as of commit 11722439fb20 (\"KVM: nVMX: Ensure\nKVM_REQ_GET_NESTED_STATE_PAGES is cleared on VM-Exit\") ensure the request\nis cleared on VM-Exit (including the \"forced\" case), i.e. there is no risk\nof double-mapping due to emulated VMLAUNCH/VMRESUME/VMRUN *and* the request\ntrying to map the nested pages."
