Null pointer dereference
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Make sure GHCB is mapped before updating Access to the GHCB is mainly in the VMGEXIT path and it is known that the GHCB will be mapped. But there are two paths where it is possible the GHCB might not be mapped. The...
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...
