Kernel: KVM: potential use-after-free via kvm_ioctl_create_device()

A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API. While creating a device via kvmioctlcreatedevice, the device holds a reference to a VM object, later this reference is transferred to the caller's file descriptor table. If suc...
