Description
With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
A flaw was found in KVM. With shadow paging enabled if INVPCID is executed with CR0.PG=0, the invlpg callback is not set, and the result is a NULL pointer dereference. This flaw allows a guest user to cause a kernel oops condition on the host, resulting in a denial of service.
