"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-1699:05 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-2016-10208
    The ext4_fill_super function in fs/ext4/super.c in the Linux kernel
    through 4.9.8 does not properly validate meta block groups, which
    allows physically proximate attackers to cause a denial of service
    (out-of-bounds read and system crash) via a crafted ext4 image.
    CVE-2016-7910
    Use-after-free vulnerability in the disk_seqf_stop function in
    block/genhd.c in the Linux kernel before 4.7.1 allows local users to
    gain privileges by leveraging the execution of a certain stop
    operation even if the corresponding start operation had failed.
    CVE-2016-8646
    The hash_accept function in crypto/algif_hash.c in the Linux kernel
    before 4.3.6 allows local users to cause a denial of service (OOPS) by
    attempting to trigger use of in-kernel hash algorithms for a socket
    that has received zero bytes of data.
    CVE-2017-5986
    Race condition in the sctp_wait_for_sndbuf function in
    net/sctp/socket.c in the Linux kernel before 4.9.11 allows local users
    to cause a denial of service (assertion failure and panic) via a
    multithreaded application that peels off an association in a certain
    buffer-full state.
    CVE-2017-7308
    The packet_set_ring function in net/packet/af_packet.c in the Linux
    kernel through 4.10.6 does not properly validate certain block-size
    data, which allows local users to cause a denial of service (integer
    signedness error and out-of-bounds write), or gain privileges (if the
    CAP_NET_RAW capability is held), via crafted system calls.
    Additional Changes:
    This update also fixes several bugs and adds various enhancements.

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