Public Exploit

Description

An issue was discovered in PassMark BurnInTest v9.1 Build 1008, OSForensics v7.1 Build 1012, and 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 BurnInTest v9.2, PerformanceTest v10.0 Build 1009, OSForensics v8.0.
