"The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2009-490:03 advisory.

    This package provides the kvm kernel modules built for the Linux kernel
    CVE-2009-3638
    Integer overflow in the kvm_dev_ioctl_get_supported_cpuid function in arch/x86/kvm/x86.c in the KVM
    subsystem in the Linux kernel before 2.6.31.4 allows local users to have an unspecified impact via a
    KVM_GET_SUPPORTED_CPUID request to the kvm_arch_dev_ioctl function.
    CVE-2009-3722
    The handle_dr function in arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 2.6.31.1 does
    not properly verify the Current Privilege Level (CPL) before accessing a debug register, which allows
    guest OS users to cause a denial of service (trap) on the host OS via a crafted application.
    CVE-2009-4031
    The do_insn_fetch function in arch/x86/kvm/emulate.c in the x86 emulator in the KVM subsystem in the Linux
    kernel before 2.6.32-rc8-next-20091125 tries to interpret instructions that contain too many bytes to be
    valid, which allows guest OS users to cause a denial of service (increased scheduling latency) on the host
    OS via unspecified manipulations related to SMP support.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
