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
The issue was addressed with improved checks. This issue is fixed in iOS 18.4 and iPadOS 18.4, iPadOS 17.7.6, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, visionOS 2.4, watchOS 11.4. An attacker on the local network may cause an unexpected app termination.

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 vulnerability in Apple operating systems allows a local network attacker to cause unexpected app termination (denial of service). The issue was addressed with improved input validation or bounds checking in the affected network handling components.

MitigationApply the vendor-supplied updates: iOS 18.4, iPadOS 18.4/17.7.6, macOS Sequoia 15.4/Sonoma 14.7.5/Ventura 13.7.5, tvOS 18.4, visionOS 2.4, or watchOS 11.4 as appropriate for affected devices.

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 type
    Determine whether the device is an iPhone, iPad, Mac, Apple TV, Apple Vision Pro, or Apple Watch. This can be done via System Settings > About (or Apple menu > About This Mac on macOS), or by checking the device model number.
    Affected if The device is any of these Apple product types running a potentially affected OS
  2. Check the installed iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About and note the Version number (e.g., 18.3.1). Compare this against the affected ranges: iOS < 18.4, or iPadOS < 17.7.6 or >= 18.0 and < 18.4.
    Affected if iOS is below 18.4, or iPadOS is below 17.7.6, or iPadOS is 18.0 through 18.3.x
  3. Check the installed macOS version
    On Mac, go to Apple menu > About This Mac and note the Version number (e.g., 15.3). Compare this against the affected ranges: macOS Ventura < 13.7.5, Sonoma < 14.7.5, or Sequoia < 15.4.
    Affected if macOS Ventura is below 13.7.5, Sonoma is below 14.7.5, or Sequoia is below 15.4
  4. Check the installed tvOS, visionOS, or watchOS version
    On Apple TV, go to Settings > General > About > Version. On Apple Vision Pro, go to Settings > General > About. On Apple Watch, open the Watch app on iPhone and go to General > About. Note the version number and compare against: tvOS < 18.4, visionOS < 2.4, or watchOS < 11.4.
    Affected if tvOS is below 18.4, visionOS is below 2.4, or watchOS is below 11.4
  5. Verify network exposure (context check)
    Determine if the device is accessible on local networks. This vulnerability is exploitable by a local network attacker. Check if file sharing, AirPlay, AirDrop, or other network services are enabled, as these may increase exposure.
    Affected if The device is on a network where untrusted local attackers could send malicious network packets

A device is affected if it runs any Apple OS version that falls below the patched versions (iOS 18.4, iPadOS 18.4/17.7.6, macOS 15.4/14.7.5/13.7.5, tvOS 18.4, visionOS 2.4, watchOS 11.4) and is reachable by a local network attacker.

  1. Back up your device data before performing any OS update
  2. For iPhone: Go to Settings > General > Software Update and install iOS 18.4
  3. For iPad: Go to Settings > General > Software Update and install iPadOS 18.4 (or iPadOS 17.7.6 if staying on iPadOS 17)
  4. For Mac: Open System Settings > General > Software Update and install macOS Ventura 13.7.5, Sonoma 14.7.5, or Sequoia 15.4 as appropriate
  5. For Apple TV: Go to Settings > System > Software Updates and install tvOS 18.4
  6. For Apple Watch: Open the Watch app on iPhone, go to General > Software Update and install watchOS 11.4
  7. For Apple Vision Pro: Go to Settings > General > Software Update and install visionOS 2.4
  8. Verify the update was successfully installed by checking the OS version in Settings
Caveat Apple point releases typically include bug fixes and security patches with minimal risk; however, always review release notes for any app compatibility notices
