Passmark Software PerformanceTest CVE-2020-15481 Privilege Escalation Vulnerability

Description

An issue was discovered in PassMark PerformanceTest v10.0 Build 1008. The kernel driver exposes IOCTL functionality that allows low-privilege users to map arbitrary physical memory into the address space of the calling process. This could lead to arbitrary Ring-0 code execution and escalation of privileges. This affects DirectIo32.sys and DirectIo64.sys drivers. This issue is fixed in PerformanceTest v10.0 Build 1009.
