Linux Distros Unpatched Vulnerability : CVE-2017-11176

high Nessus Plugin ID 220198

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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

- The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact. (CVE-2017-11176)

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

Solution

There is no known solution at this time.
