CVE-2020-15480
The kernel driver exposes IOCTL functionality that allows low-privilege users to read and write to arbitrary Model Specific Registers (MSRs).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.63%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in PassMark BurnInTest through 9.1, OSForensics through 7.1, and PerformanceTest through 10. The kernel driver exposes IOCTL functionality that allows low-privilege users to read and write to arbitrary Model Specific Registers (MSRs). This could lead to arbitrary Ring-0 code execution and escalation of privileges. This affects DirectIo32.sys and DirectIo64.sys.
