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 installed macOS versionClick the Apple menu in the top-left corner of the screen, then select 'About This Mac'. The macOS version number will be displayed below the Apple logo.Affected if The version shown is earlier than 14.4 (for example, 14.3.x, 14.2, 14.1, etc.)
-
Verify exact version number via TerminalOpen Terminal and run: sw_vers -productVersionAffected if The output is a version number lower than 14.4 (e.g., 14.3.1, 14.3, 14.2.1)
-
Confirm macOS Sonoma lineageIn 'About This Mac', verify the macOS name shows 'Sonoma' and the version is below 14.4Affected if The system is running macOS Sonoma but the build is earlier than the 14.4 security update
If the installed macOS version is any build earlier than 14.4, the system is affected by the path validation vulnerability and should be updated.
