kernel: SVM nested virtualization issue in KVM (AVIC support)

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "intctl" field, this issue could allow a malicious ...
