Field notes

amdpowerprofiler.sys is the kernel driver for AMD uProf, AMD's microarchitecture profiling and power-analysis tool for developers and performance enthusiasts. The driver provides access to Model-Specific Registers (MSRs) for detailed CPU telemetry.

CVE-2021-26334 documents a privilege-escalation vulnerability: lower-privileged users can access MSRs through the driver's interface and achieve ring-0 code execution. AMD patched the issue in later uProf releases.

If you use AMD uProf for profiling or power analysis, update to the current version.

Public CVEs

CVE-2021-26334

What this means, plainly

Presence is not proof of misuse. Driver files on the LOLDrivers list commonly ship with legitimate hardware tools, gaming software, or vendor utilities. Their presence is recorded as evidence on a record. It is never treated as a verdict about a person.
