This issue was fixed in the 4.13.0, 4.14.9, and 4.15.9 kernel versions. An out-of-bounds read flaw was found in the way the bss_INFO system information table was accessed in the Linux kernel. An attacker could use this flaw to discover potentially sensitive information about host network activities.
In addition, it was found that the; mac80211 subsystem allowed remote attackers to cause a denial of service (DoS) or possibly have unspecified other impact via a large number of malformed, race-condition laden 802.11 SET commands. A race condition can occur when there are two or more attempts to access the same memory location at the same time. An attacker could use this flaw to cause a denial of service (DoS) by causing the mac80211 subsystem to make race condition attempts to access the same memory locations.
CVE-2018-14617 It was discovered that a privileged guest user's ability to access guest physical devices could be limited by a race condition in the handling of device access requests. A privileged user in a guest virtual machine could use this flaw to escalate their privileges to that of the host virtual machine.
This issue was addressed by removing the privileged user from the user-option list in the handling of device access requests.

Virtualization of Storage Devices
Virtualization of storage devices allows for the migration of data between different physical storage devices without downtime. With this feature, you can now easily move your information from a solid-state drive to a hard disk drive or vice versa. This also has the benefit of saving space on your drives and speeding up performance by moving frequently accessed data from frequently used drives to slower ones.
