CVE-2021-47008

CVE-2021-47008 relates to the Linux kernel KVM/SVM path where GHCB is updated in SIPI handling and MSR operations. The vulnerability arises if SIPIs occur without a corresponding AP Reset Hold, risking a NULL pointer dereference when GHCB is not mapped, and similarly a potential GHCB access issue...
