"The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the
AXSA:2016-612:06 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-2016-4565
    The InfiniBand (aka IB) stack in the Linux kernel before 4.5.3
    incorrectly relies on the write system call, which allows local users
    to cause a denial of service (kernel memory write operation) or
    possibly have unspecified other impact via a uAPI interface.
    Security Fix:
    Fixed bugs:
    * When providing some services and using the Integrated Services Digital Network (ISDN), the system could
    terminate unexpectedly due to the call of the tty_ldisc_flush() function. The provided patch removes this
    call and the system no longer hangs in the described scenario.
    * An update to the Asianux Linux 6.8 kernel added calls of two functions provided by the ipv6.ko kernel
    module, which added a dependency on that module. On systems where ipv6.ko was prevented from being loaded,
    the nfsd.ko and lockd.ko modules were unable to be loaded. Consequently, it was not possible to run an NFS
    server or to mount NFS file systems as a client. The underlying source code has been fixed by adding the
    symbol_get() function, which determines if nfsd.ko and lock.ko are loaded into memory and calls them
    through function pointers, not directly. As a result, the aforementioned kernel modules are allowed to be
    loaded even if ipv6.ko is not, and the NFS mount works as expected.
    * After upgrading the kernel, CPU load average increased compared to the prior kernel version due to the
    modification of the scheduler. The provided patch set reverts the calculation algorithm of this load
    average to the the previous version thus resulting in relatively lower values under the same system load.

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
