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.

NVD · unedited
An out-of-bounds write issue was addressed with improved input validation. This issue is fixed in iOS 17.5 and iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, visionOS 1.2, watchOS 10.5. An app may be able to execute arbitrary code with kernel privileges.

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 · high confidence

This is a kernel-level out-of-bounds write vulnerability in multiple Apple operating systems (iOS, iPadOS, macOS, tvOS, visionOS, watchOS). The vulnerability allows a malicious application to write data beyond allocated memory boundaries, potentially achieving arbitrary code execution with kernel/root privileges. The issue was patched through improved input validation in the specified versions.

MitigationApply the vendor-supplied OS updates: iOS 17.5, iPadOS 17.5, macOS Sonoma 14.5, tvOS 17.5, visionOS 1.2, or watchOS 10.5. For organizations, inventory all affected devices and ensure patches are deployed across the fleet.

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 the operating system type
    Determine whether the device runs iOS, iPadOS, macOS, tvOS, visionOS, or watchOS. For macOS, run 'sw_vers' in Terminal. For iOS/iPadOS, check via MDM, Apple Configurator, or the device Settings > General > About. For tvOS/watchOS/visionOS, check via Settings > General > About on the device.
    Affected if The device runs any of the affected Apple operating systems: iOS, iPadOS, macOS, tvOS, visionOS, or watchOS.
  2. Check iOS or iPadOS version
    On the iOS/iPadOS device, go to Settings > General > About > Version, or query via MDM/Apple Configurator. Note the full version number (e.g., 17.4.1).
    Affected if The version is lower than 17.5 (for example, 17.4.x, 17.3.x, or earlier).
  3. Check macOS version
    On macOS, go to System Settings > General > About > Version, or run 'sw_vers' in Terminal. Note the version number (e.g., 14.4).
    Affected if The version is 14.0 through 14.4.x (i.e., macOS Sonoma 14.0, 14.1, 14.2, 14.3, or 14.4).
  4. Check tvOS version
    On Apple TV, go to Settings > General > About > Version, or check via MDM. Note the version number.
    Affected if The version is lower than 17.5 (for example, 17.4.x or earlier).
  5. Check visionOS version
    On Apple Vision Pro, go to Settings > General > About > Version. Note the version number.
    Affected if The version is lower than 1.2 (for example, 1.1.x or earlier).
  6. Check watchOS version
    On Apple Watch, go to Settings > General > About > Version, or check via the Watch app on paired iPhone. Note the version number.
    Affected if The version is lower than 10.5 (for example, 10.4.x or earlier).

The device is affected if it runs iOS, iPadOS, or tvOS versions below 17.5; macOS versions 14.0 through 14.4.x; visionOS versions below 1.2; or watchOS versions below 10.5.
