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 lineRun `sw_vers -productVersion` in Terminal to retrieve the installed macOS version numberAffected if The version is 10.15.7, or falls between 10.15 and 10.15.6, or between 11.0 and 11.6.5, or between 12.0 and 12.3
-
Verify system is unpatchedCheck for the presence of the security update by reviewing system update history in System Preferences > Software Update, or run `defaults read /Library/Preferences/com.apple.SoftwareUpdate.plist LastSuccessfulDate` if availableAffected if No security update from June 2022 or later has been installed
-
Confirm kernel-level exposureThis is a kernel vulnerability that requires no specific feature or configuration to be enabled - it exists in the kernel itself whenever the affected macOS version is runningAffected if The system is running any unpatched affected version regardless of configuration
A user is affected if their macOS version falls within 10.15.x (before 10.15.7), 11.0-11.6.5, or 12.0-12.3 and has not received the June 2022 security updates.
