CVE-2023-32375
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 out-of-bounds read was addressed with improved input validation. This issue is fixed in macOS Monterey 12.6.6, macOS Ventura 13.4. Processing a 3D model may result in disclosure of process memory.
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 confidenceCVE-2023-32375 is an out-of-bounds read vulnerability in macOS that occurs when processing 3D model files. The vulnerability allows a specially crafted 3D model to be parsed in a way that reads beyond allocated memory boundaries, potentially exposing sensitive process memory contents to an attacker.

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 macOS versionRun 'sw_vers -productVersion' in Terminal to obtain the currently running macOS version numberAffected if The version is 12.0.0 through 12.6.5, or 13.0 through 13.3.x (any version less than 12.6.6 or 13.4 from the affected ranges)
-
Identify 3D model processing applicationsReview installed applications that handle 3D model files such as CAD tools, 3D viewers, or modeling software. Check /Applications folder and running processes for programs that open .obj, .fbx, .dae, .3ds, or similar 3D file formatsAffected if Any application capable of opening or parsing 3D model files is installed and the macOS version falls within the affected range
-
Audit recent 3D model file accessRun 'sudo fs_usage -f filesystem | grep -i -E "\.(obj|fbx|dae|3ds|usdz)$"' or review system logs (Console app) for recent access to 3D model files, particularly from untrusted sourcesAffected if The system has recently opened or parsed 3D model files and the macOS version is within the vulnerable range
The environment is affected if macOS version is 12.0.0-12.6.5 or 13.0-13.3.x AND the system processes or has processed 3D model files.

dbcve · scoped12.6.613.4
Apply the vendor-supplied security updates: macOS Monterey 12.6.6 or later, macOS Ventura 13.4 or later. Users should avoid opening untrusted 3D model files until patches are applied.
macOS Monterey 12.6.6 or macOS Ventura 13.4 (depending on starting version)
- Check the current macOS version by clicking the Apple menu > About This Mac
- Back up important data using Time Machine or another backup solution
- Open System Preferences (or System Settings on macOS Ventura and later)
- Navigate to Software Update and check for available updates
- Install macOS Monterey 12.6.6 (if on Monterey 12.0.0-12.6.5) or macOS Ventura 13.4 (if on Ventura 13.0-13.3)
- Restart the system when prompted to complete the update
