This issue is fixed in iOS 18.6 and iPadOS 18.6, iPadOS 17.7.9, macOS Sequoia 15.6, macOS Sonoma 14.7.7, macOS Ventura 13.7.7, tvOS 18.6, visionOS 2.6, watchOS 11.6. A non-privileged user may be able to modify restricted network settings.

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 non-privileged user to modify restricted network settings, potentially leading to denial of service or network disruption. The issue was addressed with improved input validation. Affected systems include iOS 18.6, iPadOS 17.7.9 and 18.6, macOS Sequoia 15.6, Sonoma 14.7.7, Ventura 13.7.7, tvOS 18.6, visionOS 2.6, and watchOS 11.6.

MitigationApply vendor-supplied updates to all affected Apple devices. For enterprise environments, deploy updates via MDM (Mobile Device Management) or ensure end-users update their devices to the patched versions.

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 device type
    Determine whether the device is an iPhone, iPad, Mac, Apple TV, Vision Pro, or Apple Watch
    Affected if Device is any of these Apple products
  2. Check iOS or iPadOS version
    On iPhone or iPad, open Settings > General > About and note the version number (for example, 18.5 or 17.7.6)
    Affected if Version is less than 18.6, or version is 17.7.7 or higher but less than 18.6 (specifically < 17.7.7; >= 18.0, < 18.6)
  3. Check macOS version
    On Mac, open System Settings > About (or System Preferences > About on older versions) and note the version number (for example, 15.5 or 14.7.6)
    Affected if Version is less than 13.7.7, or between 14.0 and 14.7.7 (exclusive), or between 15.0 and 15.6 (exclusive)
  4. Check tvOS, visionOS, or watchOS version
    On Apple TV, open Settings > General > About. On Vision Pro or Apple Watch, open Settings > General > About and note the version number
    Affected if tvOS version is less than 18.6; visionOS version is less than 2.6; watchOS version is less than 11.6

A user is affected if their device runs any of the listed Apple OS versions within the vulnerable ranges, which can be verified by checking the OS version in the device settings.
