"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-1648:04 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any
    Linux operating system.  The kernel handles the basic functions
    of the operating system: memory allocation, process allocation, device
    input and output, etc.
    Security issues fixed with this release:
    CVE-2016-8650
    The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through
    4.8.11 does not ensure that memory is allocated for limb data, which
    allows local users to cause a denial of service (stack memory
    corruption and panic) via an add_key system call for an RSA key with a
    zero exponent.
    CVE-2016-9793
    The sock_setsockopt function in net/core/sock.c in the Linux kernel
    before 4.8.14 mishandles negative values of sk_sndbuf and sk_rcvbuf,
    which allows local users to cause a denial of service (memory
    corruption and system crash) or possibly have unspecified other impact
    by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt
    system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option.
    CVE-2017-2618
    ** RESERVED **
    This candidate has been reserved by an organization or individual that
    will use it when announcing a new security problem.  When the
    candidate has been publicized, the details for this candidate will be
    provided.
    CVE-2017-2636
    Race condition in drivers/tty/n_hdlc.c in the Linux kernel through
    4.10.1 allows local users to gain privileges or cause a denial of
    service (double free) by setting the HDLC line discipline.
    These updated kernel packages include several security issues and numerous bug fixes.

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
