CVE-2019-6974 is a use-after-free vulnerability in the Linux kernel KVM device-control API, affecting kernels before 4.20.8. In kvm_ioctl_create_device(), a device file descriptor can be installed before the associated VM object reference is safely acquired. The device retains a VM reference that is transferred through the caller's file-descriptor table; closing the descriptor can reduce the VM object's reference count to zero, leaving subsequent accesses to freed memory possible.
