Summary

AMD μProf (“MICRO-prof”) is a software profiling analysis tool for x86 applications running on Windows, Linux and FreeBSD operating systems and provides event information unique to the AMD “Zen” microarchitecture based platforms and AMD INSTINCT™ MI Series accelerators. AMD μProf enables the developer to better understand application performance and evaluate potential improvements.

An external researcher reported three potential vulnerabilities in AMD μProf caused by insufficient validation of inputs to the IOCTL (Input Output Control) buffer. These vulnerabilities may allow an authenticated user to potentially cause a Windows crash leading to denial of service (DoS). Alternatively, an authenticated user may load an unsigned driver potentially leading to arbitrary kernel execution.

CVE Details

Refer to Glossary for explanation of terms

CVE Severity CVE Description
CVE-2023-20562 High Insufficient validation in the IOCTL (Input Output Control) input buffer in AMD uProf may allow an authenticated user to load an unsigned driver potentially leading to arbitrary kernel execution.
CVE-2023-20556 Medium Insufficient validation of the IOCTL (Input Output Control) input buffer in AMD μProf may allow an authenticated user to send an arbitrary buffer potentially resulting in a Windows crash leading to denial of service.
CVE-2023-20561 Medium Insufficient validation of the IOCTL (Input Output Control) input buffer in AMD μProf may allow an authenticated user to send an arbitrary address potentially resulting in a Windows crash leading to denial of service.
