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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the     Linux kernel through 4.13.3. This function does not check whether the required attributes are present in a     Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in     a NULL pointer dereference and system crash. (CVE-2017-12153)

Note that Nessus relies on the presence of the package as reported by the vendor.
