UBUNTU-CVE-2021-3653

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 ...

arch/x86/kvm/svm/nested.c in the Linux kernel before 5.11.12 has a use-after-free in which an AMD KVM guest can bypass access control on host OS MSRs when there are nested guests aka CID-a58d9166a756. This occurs because of a TOCTOU race condition associated with a VMCB12 double fetch in nested_svm_vmrun.
