CVE-2020-12981
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn insufficient input validation in the AMD Graphics Driver for Windows 10 may allow unprivileged users to unload the driver, potentially causing memory corruptions in high privileged processes, which can lead to escalation of privileges or denial of service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is a local privilege escalation vulnerability in the AMD Graphics Driver for Windows 10. Insufficient input validation allows unprivileged users to unload the kernel-mode driver, causing memory corruption in high-privileged (SYSTEM) processes. This can lead to arbitrary code execution with elevated privileges or system crash (DoS).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed AMD Radeon Software versionOpen Control Panel > Programs and Features, look for 'AMD Radeon Software' or 'AMD Catalyst Control Center' and note the version number displayed. Alternatively, check the registry at HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'AMD' or 'Radeon' and retrieve the DisplayVersion value.Affected if The installed version is lower than 20.7.1 for AMD Radeon Software, or lower than 21.q1 for AMD Radeon Pro Software.
-
Check AMD graphics driver version in Device ManagerOpen Device Manager, expand 'Display adapters', right-click the AMD GPU device, select 'Properties', go to the 'Driver' tab, and record the Driver Version. This shows the kernel driver version (atikmdag.sys).Affected if The driver version string is lower than 27.20.7.1 (which corresponds to software version 20.7.1).
-
Verify AMD kernel driver is loadedOpen Command Prompt as any user and run 'sc query atikmdag' to query the status of the AMD kernel driver service (atikmdag.sys).Affected if The service exists and is in a running state, indicating the vulnerable driver component is active.
-
Confirm unprivileged user contextVerify you are running from a standard user account (non-admin). Run 'whoami /groups' and confirm the output does not include 'BUILTIN\Administrators' or 'S-1-5-32-544'.Affected if The check is performed from an unprivileged account, because the vulnerability specifically allows unprivileged users to unload the driver.
You are affected if an AMD graphics driver version below 20.7.1 (Radeon Software) or below 21.q1 (Radeon Pro Software) is installed and loaded on Windows 10, and the system has unprivileged user access to potentially trigger driver unload.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data20.7.121.q1
Apply the AMD-provided driver update that addresses the input validation vulnerability. Restrict driver unloading permissions via Group Policy or registry controls as a defense-in-depth measure until the patch is deployed.
