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 device type and operating systemDetermine whether the device is an iPhone (iOS), iPad (iPadOS), or Mac (macOS). On iPhone/iPad, go to Settings > General > About. On Mac, click the Apple menu and select About This Mac.Affected if Device runs iOS, iPadOS, or macOS Ventura
-
Check iOS or iPadOS versionOn iPhone or iPad, go to Settings > General > About and look at the 'Version' field. Note the full version number (e.g., 17.5, 16.7.8).Affected if Version is shown as less than 16.7.9, or as 17.0 through 17.5.x (anything below 17.6)
-
Check macOS Ventura versionOn Mac, click Apple menu > About This Mac. Look at the macOS version number (e.g., 13.6, 13.5.1). Note that this vulnerability affects only macOS Ventura, not later versions like macOS Sonoma.Affected if macOS Ventura version is shown as less than 13.6.8 (e.g., 13.6.7, 13.5, 13.4)
-
Compare against affected version rangesUse these thresholds: for iOS/iPadOS, vulnerable if version < 16.7.9 OR version is 17.0-17.5.x; for macOS Ventura, vulnerable if version < 13.6.8. If your device shows a version in these ranges, it is affected by this CVE.Affected if Installed version falls within any of the vulnerable ranges
A device is affected if it runs iOS or iPadOS version 16.7.8 or earlier, 17.0 through 17.5.x, or macOS Ventura 13.6.7 or earlier.
