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.
-
Identify the Apple operating systemDetermine whether the device runs iOS, iPadOS, macOS Monterey, tvOS, or watchOS. This can be done via System Preferences on macOS, Settings > General > About on iOS/iPadOS, or the Settings app on tvOS/watchOS.Affected if The device runs any of the affected Apple operating systems listed in the CVE (iOS, iPadOS, macOS, tvOS, or watchOS)
-
Check iOS or iPadOS versionOn the device, go to Settings > General > About and note the version number displayed next to 'Version'.Affected if The version is lower than 15.4 (for example, 15.3.1, 15.3, 15.2, etc.)
-
Check macOS Monterey versionClick the Apple menu > About This Mac. The version number appears below the macOS name (for example, 12.2.2, 12.2.1, 12.2, 12.1).Affected if The version is 12.0 through 12.2.x (any version >= 12.0 but < 12.3)
-
Check tvOS versionGo to Settings > General > About > Version on the Apple TV device.Affected if The version is lower than 15.4
-
Check watchOS versionOn the paired iPhone, open the Watch app, go to General > About, and note the watchOS version. Alternatively, on the Apple Watch, go to Settings > General > About.Affected if The version is lower than 8.5
A device is affected if it runs iOS/iPadOS/tvOS/watchOS versions below 15.4/8.5 respectively, or macOS Monterey 12.0 through 12.2.x (any version >= 12.0 but < 12.3).
