Official Description
The cbstream.sys driver in Carbon Black 5.1.1.60603 allows local users with admin privileges to cause a denial of service (out-of-bounds read and system crash) via a large counter value in an 0x62430028 IOCTL call.
Technical Analysis
CVE-2016-9569 requires local access, meaning attackers must already have a foothold on the target system.
