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.

dbcve analysis · moderate confidence

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. Identify your Apple device type
    Determine if the device is an iPhone, iPad, Mac, Apple TV, Apple Watch, or Apple Vision Pro
    Affected if Device runs any of the affected Apple operating systems (iOS, iPadOS, macOS, tvOS, watchOS, visionOS)
  2. Check iOS or iPadOS version
    Open Settings > General > About and note the version number (for example, 18.3 or 26.2)
    Affected if Version is less than 18.7.5, or falls between 26.0 and 26.3 (exclusive)
  3. Check macOS version
    Open System Settings > About This Mac or run 'sw_vers' in Terminal, note the version number (for example, 14.4 or 15.5)
    Affected if Version is 14.0 to 14.8.4 (exclusive), 15.0 to 15.7.4 (exclusive), or 26.0 to 26.3 (exclusive)
  4. Check tvOS, watchOS, or visionOS version
    Open Settings > General > About on Apple TV, Apple Watch, or Apple Vision Pro, note the version number
    Affected if Version is less than 26.3

You are affected if your device runs any Apple OS version within the ranges specified: iOS/iPadOS below 18.7.5 or between 26.0-26.2, macOS below 14.8.4 or 15.7.4 or 26.0-26.2, or any tvOS/watchOS/visionOS below 26.3.
