Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

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

A bounds checking vulnerability in image processing components allows a maliciously crafted image to trigger an out-of-bounds read, potentially exposing sensitive user information. The fix implements proper boundary validation during image parsing operations.

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 iOS version on iPhone
    Go to Settings > General > About > Software Version or run 'sw_vers' in Terminal on macOS if the iPhone is connected
    Affected if Version is below 18.7.5 OR between 26.0 and 26.2 (exclusive of 26.3)
  2. Check iPadOS version on iPad
    Go to Settings > General > About > Software Version or run 'sw_vers' in Terminal on macOS if the iPad is connected
    Affected if Version is below 18.7.5 OR between 26.0 and 26.2 (exclusive of 26.3)
  3. Check macOS version on Mac
    Go to System Settings > About or run 'sw_vers' in Terminal
    Affected if Version is 14.0 to 14.8.3, 15.0 to 15.7.3, or 26.0 to 26.2 (exclusive of 26.3)
  4. Check tvOS version on Apple TV
    Go to Settings > General > About > Version or use the Remote: Settings > General > About
    Affected if Version is below 26.3 (any version starting from initial release up to 26.2)
  5. Check visionOS version on Apple Vision Pro
    Go to Settings > General > About > Software Version
    Affected if Version is below 26.3 (any version up to 26.2)
  6. Check watchOS version on Apple Watch
    Open the Watch app on iPhone > General > About, or go to Settings > General > About on the Watch itself
    Affected if Version is below 26.3 (any version up to 26.2)

You are affected if your device runs any iOS, iPadOS, macOS, tvOS, visionOS, or watchOS version that falls within the ranges listed as vulnerable for that product.
