CVE-2018-6593
Improper access control in zam32.sys and zam64.sys allows a non-privileged process to register itself with the driver by connecting to the filter communication port and then using IOCTL 0x8000204C to \\.\ZemanaAntiMalware to elevate privileges.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
