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.
-
Determine the installed macOS versionRun the command 'sw_vers -productVersion' in Terminal, or go to Apple menu > About This Mac to view the version numberAffected if The version displayed falls within any of these ranges: 10.15.7 (Catalina), 11.0-11.6.5 (Big Sur), or 12.0-12.3 (Monterey)
-
Identify the macOS release nameUse the version number from step 1: 10.x is Catalina, 11.x is Big Sur, 12.x is MontereyAffected if The release corresponds to an affected version range from step 1
-
Confirm the specific patch stateCheck if Security Update 2022-004 or later has been installed by reviewing the installed updates in System Preferences > Software Update, or by running 'defaults read /Library/Preferences/com.apple.SoftwareUpdate.plist LastSuccessfulDate'Affected if The system shows no recent security updates installed since mid-2022 and the version matches an affected release
