CVE-2019-5146
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 exploitable out-of-bounds read vulnerability exists in AMD ATIDXX64.DLL driver, version 26.20.13025.10004. A specially crafted pixel shader can cause a denial of service. An attacker can provide a specially crafted shader file to trigger this vulnerability. This vulnerability can be triggered from VMware guest, affecting VMware host.
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 · moderate confidenceAn out-of-bounds read vulnerability exists in AMD ATIDXX64.DLL graphics driver (version 26.20.13025.10004). A specially crafted pixel shader can trigger the vulnerability, causing a denial of service. The vulnerability can be triggered from a VMware guest, affecting the VMware host.

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.
-
Locate the ATIDXX64.DLL fileSearch for atidxx64.dll in the system drivers directory (commonly C:\Windows\System32\drivers\ or C:\Windows\System32\)Affected if The file exists on the system, indicating an AMD graphics driver is installed
-
Identify the DLL file versionRight-click the atidxx64.dll file, select Properties, and view the File Version field under the Details tabAffected if The version number displayed is exactly 26.20.13025.10004
-
Confirm AMD graphics driver installationOpen Device Manager, expand Display adapters, and verify an AMD GPU driver is installedAffected if An AMD graphics adapter driver is present in the system
-
Determine if pixel shader operations are in useCheck if graphics applications or VMware virtual machines with 3D graphics acceleration are runningAffected if Pixel shader-enabled applications or VM with 3D acceleration are active, providing a potential attack vector
-
Assess VMware environment exposureIf running VMware, check if guest machines have 3D graphics acceleration enabled (VM Settings > Hardware > Display > Accelerate 3D graphics)Affected if VMware guest machines have 3D graphics acceleration enabled, allowing guest-to-host trigger potential
The system is affected if atidxx64.dll version 26.20.13025.10004 is installed and pixel shader or VMware 3D-accelerated guest operations are possible.

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 dataUpdate AMD graphics drivers to the latest version. For virtualized environments, ensure VMware tools are updated and review guest-to-host isolation settings.
