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 macOS versionClick the Apple menu, select 'About This Mac', and note the version number displayed under the macOS nameAffected if The version shown is 11.0 through 11.6.x, or 12.0.0 through 12.5.x
-
Check build number via TerminalRun the command 'sw_vers -buildVersion' in Terminal to get the specific build numberAffected if The build number corresponds to an unpatched release within the vulnerable version ranges
-
Verify security update statusOpen System Settings > General > Software Update to check if the latest security updates are installedAffected if Software Update shows no pending updates but the base macOS version falls within the vulnerable ranges
You are affected if your macOS version is 11.0 to 11.6.x or 12.0.0 to 12.5.x and you have not applied the security updates for macOS 11.7 or 12.6 respectively.
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 · scoped11.712.6
Apply the security updates for macOS Big Sur 11.7, macOS Monterey 12.6, or macOS Ventura 13 and later to address the kernel memory handling flaw.
macOS 11.7 (Big Sur) or macOS 12.6 (Monterey) or macOS 13 (Ventura)
- Back up your Mac using Time Machine or another backup solution before proceeding with the system upgrade.
- Check your current macOS version by clicking the Apple menu > About This Mac.
- For macOS Big Sur (11.x) users: Upgrade to macOS 11.7 by opening System Preferences > Software Update, or download and install the macOS 11.7 update from Apple Support.
- For macOS Monterey (12.x) users: Upgrade to macOS 12.6 by opening System Preferences > Software Update, or download and install the macOS 12.6 update from Apple Support.
- Alternatively, upgrade to macOS Ventura 13 which also contains the fix for this vulnerability.
- After upgrading, verify the update was successful by checking About This Mac to confirm you are running a fixed version (11.7, 12.6, or 13+).
