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 your Apple device typeDetermine if the device is an iPhone, iPad, or Mac. On iOS/iPadOS, go to Settings > General > About. On macOS, click the Apple menu > About This Mac.Affected if Device is an iPhone, iPad, or Mac running an affected operating system
-
Check iOS or iPadOS versionOn iPhone or iPad, go to Settings > General > About and note the version number displayed next to 'Version'.Affected if Version is lower than 18.7 (for example, 18.6.x or earlier)
-
Check macOS versionOn Mac, click the Apple menu > About This Mac. The version number appears below the macOS name (for example, 15.6, 14.7, etc.).Affected if Version is 15.0 to 15.6.x (affected in macOS Sequoia) or 14.0 to 14.7.x (affected in macOS Sonoma)
-
Verify macOS Tahoe version if applicableIf the Mac is running a newer macOS release named Tahoe, check the version in About This Mac.Affected if Version is lower than 26 (the fixed release for macOS Tahoe)
You are affected if your device runs iOS or iPadOS versions earlier than 18.7, or macOS versions 14.0-14.7.x or 15.0-15.6.x, or any macOS Tahoe version earlier than 26.
