CVE-2022-32936
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 Ventura 13. An app may be able to disclose kernel 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 confidenceA kernel-level out-of-bounds read vulnerability in macOS allowed a malicious application to read beyond allocated memory boundaries, potentially exposing kernel memory contents. The vulnerability was addressed through improved input validation, with the fix included in macOS Ventura 13.

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 macOS version via command lineOpen Terminal and run: sw_vers -productVersionAffected if The output shows a version lower than 13.0 (e.g., 12.x, 11.x, etc.)
-
Check macOS version via System SettingsOpen System Settings (or System Preferences on older macOS), go to About This Mac, and note the version displayed under the macOS nameAffected if The version shown is below 13.0 (Ventura)
-
Identify macOS release name for contextRun: sw_vers -productVersionExtra and compare against known macOS release names (Ventura = 13.0, Monterey = 12.0, Big Sur = 11.0, etc.)Affected if The system is running any macOS version prior to Ventura 13.0
A system is affected if it is running any version of macOS earlier than 13.0 (Ventura), as the vulnerability exists in the kernel of those versions and the fix was first included in macOS Ventura 13.

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 · scoped13.0
Deploy macOS Ventura 13 or later to affected systems to resolve the out-of-bounds read vulnerability and prevent kernel memory disclosure.
macOS Ventura 13.0 or later
- Back up your Mac using Time Machine or another backup solution before proceeding with the upgrade
- Upgrade to macOS Ventura 13.0 or later by going to System Preferences > Software Update, or download and install macOS Ventura from the Mac App Store
- After installation, verify the kernel memory disclosure vulnerability is resolved by confirming macOS version 13.0 or later is running (Apple menu > About This Mac)
