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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify your Apple device type
    On iOS/iPadOS, go to Settings > General > About > Model Name. On macOS, click the Apple menu and select About This Mac.
    Affected if Device is an iPhone, iPad, or Mac running iOS, iPadOS, or macOS respectively.
  2. Check iOS or iPadOS version
    Go to Settings > General > About > Version and note the numeric version (e.g., 17.2.1).
    Affected if Running iOS or iPadOS version greater than 16.0 and less than 16.7.5, OR greater than 17.0 and less than 17.3.
  3. Check macOS version
    Click Apple menu > About This Mac and note the version number displayed (e.g., 14.2).
    Affected if Running macOS version 14.0 or later but earlier than 14.3.
  4. Confirm WebKit-based browser usage
    Determine if Safari, or any app using WebKit (the Apple web engine), is in use. On iOS/iPadOS, Safari is the primary WebKit browser. On macOS, Safari uses WebKit.
    Affected if The vulnerability is triggered by processing malicious web content through WebKit-based browsers or rendering engines.

You are affected if your device runs iOS or iPadOS versions 16.7.4 or earlier (16.x), 17.0-17.2.x, or macOS Sonoma 14.0-14.2.x, AND you use WebKit-based browsers to process untrusted web content.

Recommended fix High confidence

iOS 16.7.5 or iOS 17.3 (iPhone), iPadOS 16.7.5 or iPadOS 17.3 (iPad), macOS Sonoma 14.3 (Mac)

  1. Back up your device data before initiating the update
  2. For iPhone: Go to Settings > General > Software Update and install iOS 16.7.5 (if on iOS 16.x) or iOS 17.3 (if on iOS 17.x)
  3. For iPad: Go to Settings > General > Software Update and install iPadOS 16.7.5 (if on iPadOS 16.x) or iPadOS 17.3 (if on iPadOS 17.x)
  4. For Mac: Go to System Settings > General > Software Update and install macOS Sonoma 14.3
  5. Verify the update was successful by checking the version in Settings > General > About
Caveat Minor iOS/macOS updates typically have minimal breaking changes; ensure backups before updating
