Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check iPhone or iPad OS version
    On the device, go to Settings > General > About and note the version number displayed next to 'Version'
    Affected if The version is less than 18.4 for iOS, or less than 17.7.6 OR between 18.0 and 18.4 for iPadOS
  2. Check macOS version
    Click the Apple menu > About This Mac and note the version number shown (such as 13.x, 14.x, or 15.x)
    Affected if The version is 13.0 to 13.7.4, 14.0 to 14.7.4, or 15.0 to 15.3 (meaning less than the 13.7.5, 14.7.5, or 15.4 security updates)
  3. Check visionOS version
    On Apple Vision, go to Settings > General > About and locate the version number
    Affected if The version is less than 2.4
  4. Confirm vulnerability scope
    This is a buffer overflow in core operating system components - no specific feature, configuration, or module needs to be enabled for the flaw to exist
    Affected if The device runs any affected OS version listed above and has not applied the vendor security update

A user is affected if their device runs iOS/iPadOS below 18.4 (or below 17.7.6 for iPadOS 17), macOS below 13.7.5/14.7.5/15.4, or visionOS below 2.4.
