The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:1125 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that     can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device     could use this flaw to increase their privileges on the system. (CVE-2017-2636, Important)

    Red Hat would like to thank Alexander Popov for reporting this issue.

    Bug Fix(es):

    * Previously, memory allocation in the libceph kernel module did not work correctly. Consequently, the     file system on a RADOS Block Device(RBD) could become unresponsive in the situations under high memory     pressure. With this update, the underlying source code has been fixed, and the file system no longer hangs     in the described scenario. (BZ#1418314)

    * Previously, the mpt3sas driver incorrectly checked the Transport Layer Retries (TLR) state even on     Redundant Array Of Independent Discs (RAID) devices. Consequently, a kernel panic occurred when mpt3sas     attempted to read from the RAID devices. With this update, mpt3sas has been fixed to check the TLR state     only for non-RAID devices, and the kernel no longer panics under the described circumstances. (BZ#1427453)

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