AMD μProf Security Bulletin
Bulletin ID: AMD-SB-7003
Potential Impact: Varies by CVE, see descriptions below
Severity: Varies by CVE, see descriptions below
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.
