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
A null pointer dereference was addressed with improved input validation. This issue is fixed in iOS 18.3 and iPadOS 18.3, iPadOS 17.7.6, macOS Sequoia 15.3, macOS Sonoma 14.7.5, macOS Ventura 13.7.5. An attacker on the local network may be able to cause a denial-of-service.

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. Identify the Apple device and operating system
    On iOS/iPadOS: go to Settings > General > About and note the device model and iOS/iPadOS version. On macOS: go to System Settings > About or use System Profiler and note the macOS version and Mac model.
    Affected if The device is an iPhone, iPad, or Mac running an affected OS version
  2. Check iOS or iPadOS version
    On the device, go to Settings > General > About > Version. Compare the displayed version number to the affected range: any version below 18.3 is vulnerable.
    Affected if iOS or iPadOS version is less than 18.3
  3. Check macOS version
    Click the Apple menu > About This Mac. Note the macOS version number (such as 15.1, 15.2, etc.). Compare to the affected range: versions 15.0 through 15.2.x are vulnerable.
    Affected if macOS version is 15.0, 15.1, 15.2, or 15.2.x (any version >= 15.0 but < 15.3)
  4. Determine network exposure
    Verify if the device has network connectivity enabled (Wi-Fi or Ethernet). The vulnerability is exploitable by an attacker on the local network.
    Affected if The device is connected to a network and runs a vulnerable OS version

A device is affected if it is an iPhone running iOS < 18.3, an iPad running iPadOS < 18.3, or a Mac running macOS Sequoia version 15.0-15.2.x, and the device has network connectivity.

Interim mitigation

Apply the available security updates: iOS 18.3, iPadOS 18.3/17.7.6, or macOS Sequoia 15.3/Sonoma 14.7.5/Ventura 13.7.5 depending on the affected device.

Recommended fix High confidence

iOS 18.3/iPadOS 18.3 (or iPadOS 17.7.6 for older iPads), macOS Sequoia 15.3/macOS Sonoma 14.7.5/macOS Ventura 13.7.5

  1. For iOS/iPadOS devices: 1) Back up your device data to iCloud or computer. 2) Connect your device to power and Wi-Fi. 3) Go to Settings > General > Software Update. 4) Download and install iOS 18.3 or iPadOS 18.3. For iPadOS 17.x devices, install iPadOS 17.7.6.
  2. For macOS devices: 1) Back up your Mac using Time Machine. 2) Go to System Settings > General > Software Update. 3) Download and install the appropriate security update: macOS Sequoia 15.3, macOS Sonoma 14.7.5, or macOS Ventura 13.7.5 depending on your current macOS version.
Caveat Standard OS update risks apply - ensure backups before upgrading. Review app compatibility if running older macOS versions.
