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 iOS version on iPhoneOpen Settings > General > About and look at the 'Version' fieldAffected if Version is lower than 18.2 (e.g., 18.1, 18.0, 17.x)
-
Check iPadOS version on iPadOpen Settings > General > About and look at the 'Version' fieldAffected if Version is lower than 18.2 (e.g., 18.1, 18.0, 17.x)
-
Check macOS version via System SettingsOpen System Settings (or System Preferences) > About, or click Apple menu > About This Mac, and note the version number under the macOS nameAffected if Version is lower than 15.2 (e.g., 15.1, 15.0, 14.x)
-
Check macOS version via command lineRun 'sw_vers -productVersion' in TerminalAffected if Output is lower than 15.2 (e.g., 15.1, 15.0, 14.x)
The device is affected if it runs iOS or iPadOS below 18.2, or macOS Sequoia below 15.2, since the vulnerability exists in those earlier versions and was patched in the 18.2 and 15.2 releases respectively.

Apply the available vendor patches by updating affected devices to iOS 18.2/iPadOS 18.2 or macOS Sequoia 15.2 or later.
iOS 18.2, iPadOS 18.2, macOS Sequoia 15.2
- Back up your device before updating
- Check current iOS/iPadOS version via Settings > General > About, or macOS version via System Settings > General > About
- For iOS/iPadOS: Navigate to Settings > General > Software Update and install iOS 18.2 or iPadOS 18.2
- For macOS: Navigate to System Settings > General > Software Update and install macOS Sequoia 15.2
- Alternatively, connect iOS/iPadOS device to Finder/iTunes on a Mac to update via computer
- Restart the device after update completes
- Verify the update was successful by checking Settings > General > About shows version 18.2 (iOS/iPadOS) or 15.2 (macOS)
