CVE-2023-20510
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 DRAM address validation in PMFW may allow a privileged attacker to read from an invalid DRAM address to SRAM, potentially resulting in data corruption 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 · moderate confidenceThis is a firmware vulnerability in AMD Platform Management Firmware (PMFW) where insufficient validation of DRAM addresses allows a privileged attacker to read from invalid DRAM addresses into SRAM. This improper address checking can lead to data corruption or 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 AMD Radeon Software versionOpen AMD Radeon Software settings, navigate to the 'About' or 'System' section to view the installed software version numberAffected if Version is below 23.12.1 or is version 23.q4 (23.4, 23.7, 23.10)
-
Confirm version numbering schemeCheck if the installed version uses the quarterly format (YY.Q format such as 23.4, 23.7, 23.10) or the dated format (23.12.1)Affected if Using quarterly versioning (23.x) where x is less than 12, or dated version lower than 23.12.1
-
Verify hardware platform typeDetermine if the system uses an AMD processor with Platform Management Firmware capabilities (APUs, certain server/workstation processors)Affected if System contains AMD hardware that utilizes PMFW for platform management
-
Check PMFW component statusOn affected AMD systems, use AMD's system utilities or firmware tools to query the current Platform Management Firmware version if accessibleAffected if PMFW is present and the firmware version corresponds to the vulnerable software release timeline
User is affected if AMD Radeon Software version is below 23.12.1 or is any 23.x quarterly release (23.4, 23.7, 23.10) running on hardware that utilizes AMD Platform Management Firmware.

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 · scoped23.12.1
Apply the vendor-supplied firmware update for PMFW that implements proper DRAM address validation bounds checking.
Radeon Software 23.12.1 or later
- Visit AMD's official support page at www.amd.com and navigate to the Drivers & Support section for Radeon graphics products
- Locate the Radeon Software driver version 23.12.1 or later (any version higher than 23.12.1)
- Download the appropriate driver for your specific graphics card model
- Run the installer and follow the on-screen prompts to update the Radeon Software
- Restart your computer after the installation completes to ensure the PMFW update is applied
