CVE-2023-31320
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 · uneditedImproper input validation in the AMD RadeonTM Graphics display driver may allow an attacker to corrupt the display potentially resulting in 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 · moderate confidenceImproper input validation in AMD Radeon Graphics display drivers allows potentially malicious or malformed input data to be processed by the driver, leading to display corruption and denial of service conditions.

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.
-
Identify installed AMD GPU modelOpen Device Manager, expand 'Display adapters', and note the exact AMD GPU model name (e.g., Radeon RX Vega 56, Radeon RX Vega 64, Radeon Pro Vega 56, Radeon Pro Vega 64)Affected if The GPU is any of the four listed Vega models (RX Vega 56, RX Vega 64, Pro Vega 56, Pro Vega 64)
-
Check AMD Radeon Software driver version on WindowsOpen AMD Radeon Software, click the gear icon, select 'System' > 'Software', and note the 'Driver Version' displayed (or run 'dxdiag' and check the display driver version under the Notes tab)Affected if The driver version is lower than 23.7.1 (or lower than the 23.q3 release if that naming applies)
-
Check driver version via PowerShell or CLIRun 'Get-WmiObject Win32_VideoController | Select-Object Name, DriverVersion' in PowerShell to retrieve the installed display driver versionAffected if The reported driver version is lower than 23.7.1
-
Verify firmware version for affected Vega GPUsFor systems with Vega 56/64 GPUs, check the VBIOS/firmware version through AMD Radeon Software 'Performance' tab > 'Tuning' or via GPU-Z utility under the 'BIOS' sectionAffected if The system has any of the four affected Vega firmware variants and no driver update has been applied
A system is affected if it runs any AMD Radeon Software version below 23.7.1, or if it contains a Radeon RX Vega 56/64 or Radeon Pro Vega 56/64 GPU with an unpatched driver.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped23.q323.7.1
Apply AMD vendor-supplied graphics driver updates to patch the input validation vulnerability; organizations should inventory affected systems and deploy tested driver updates.
Radeon Software 23.7.1 or later (or 23.q3 and later)
- 1. Visit the AMD support website (amd.com/support) to download the latest Radeon Software
- 2. Download Radeon Software version 23.7.1 or later (or version 23.q3 and later) for your specific GPU model
- 3. Run the downloaded installer and follow the prompts to update the AMD Radeon Graphics display driver
- 4. Restart your computer to complete the driver installation
