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 version on iPhoneGo to Settings > General > About and look at the Version numberAffected if Version is below 18.4 (for example, 18.3.x or earlier)
-
Check iPadOS version on iPadGo to Settings > General > About and look at the Version numberAffected if Version is below 18.4 (for example, 18.3.x or earlier)
-
Check macOS versionClick Apple menu > About This Mac and view the macOS versionAffected if Version is below 15.4 (for example, 15.3.x or earlier, also known as macOS Sequoia versions before 15.4)
-
Check tvOS versionGo to Settings > General > About > Version on Apple TVAffected if Version is below 18.4 (for example, 18.3.x or earlier)
-
Check visionOS versionGo to Settings > General > About on Apple Vision ProAffected if Version is below 2.4 (for example, 2.3.x or earlier)
A device is affected if it runs any of the listed Apple operating systems at a version lower than the patched release (iOS/iPadOS/tvOS < 18.4, macOS < 15.4, visionOS < 2.4) and is connected to a local network where an untrusted attacker could send malicious network requests.
