CVE-2023-32382
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 Big Sur 11.7.7, 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 · high confidenceThis is an out-of-bounds read vulnerability in macOS that occurs when processing 3D models. The flaw allows an attacker to read process memory beyond allocated boundaries due to insufficient input validation on 3D model data. This can lead to disclosure of sensitive process memory contents.

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 your macOS versionRun 'sw_vers' in Terminal or go to Apple menu > About This Mac to view the macOS version numberAffected if The version shown is 11.0 to 11.7.6, 12.0.0 to 12.6.5, or 13.0 to 13.3 (any version in the affected ranges)
-
Verify the specific macOS release numberRun 'sw_vers -productVersion' to get the exact version such as 11.7.5 or 13.3.1Affected if The version is less than 11.7.7, 12.6.6, or 13.4 respectively for your major release
-
Identify if 3D model processing occursCheck if users on this system commonly open or preview 3D model files (.obj, .dae, .usdz, .stl, .fbx) using built-in macOS apps like Quick Look or PreviewAffected if The system runs a vulnerable macOS version AND is used to open or preview untrusted 3D model files
-
Review Quick Look preview handlersRun 'qlmanage -m' to list Quick Look plugins, which handle 3D model previews in FinderAffected if The system runs a vulnerable macOS version and Quick Look is enabled for 3D model file types
You are affected if your macOS version falls within 11.0 to 11.7.6, 12.0.0 to 12.6.5, or 13.0 to 13.3 and you or any user on the system processes 3D model files using built-in macOS features.

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 · scoped11.7.712.6.613.4
Update macOS to version Big Sur 11.7.7, Monterey 12.6.6, Ventura 13.4 or later to patch the vulnerability. Avoid processing untrusted 3D model files until systems are patched.
macOS Big Sur 11.7.7, macOS Monterey 12.6.6, or macOS Ventura 13.4 (depending on your current major version)
- Open the Apple menu and select System Settings (or System Preferences on older macOS versions)
- Click on General, then select Software Update
- Allow macOS to check for available updates
- If the fixed version (11.7.7, 12.6.6, or 13.4) is shown, click Update Now to install it
- Restart your Mac if prompted to complete the installation
