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 the installed macOS versionOpen System Settings > General > About, or run `sw_vers -productVersion` in TerminalAffected if The version displayed is 14.0, 14.1, 14.2, 14.3, or any 14.3.x point release (anything >= 14.0 but < 14.4)
-
Verify the Security Update installation statusOpen System Settings > General > Software Update to confirm whether the Sonoma 14.4 security update has been installedAffected if The 14.4 security update is not listed as installed or the system still shows a version below 14.4
The system is affected if it is running macOS Sonoma 14.0 through 14.3.x and has not received the 14.4 security update.
