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/iPadOS versionOn the device, go to Settings > General > About > Version to see the installed iOS or iPadOS version numberAffected if Version is below 16.2 (for example, 16.1, 16.0, 15.x, or earlier)
-
Check tvOS versionOn Apple TV, go to Settings > General > About > Version to see the installed tvOS version numberAffected if Version is below 16.2 (for example, 16.1, 16.0, 15.x, or earlier)
-
Confirm device is an affected Apple mobile deviceVerify the device is an iPhone, iPad, or iPad mini by checking Settings > General > About > Model NameAffected if Device is an iPhone or iPad running iOS/iPadOS lower than version 16.2
-
Confirm device is an affected Apple TVVerify the device is an Apple TV model by checking Settings > General > About > ModelAffected if Device is an Apple TV running tvOS lower than version 16.2
The environment is affected if any iPhone, iPad, or Apple TV device is running iOS, iPadOS, or tvOS version lower than 16.2, as the vulnerability exists in the TIFF parsing component of those OS versions.
