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
This issue was addressed with improved authentication. This issue is fixed in iOS 18.7.7 and iPadOS 18.7.7, iOS 26.4 and iPadOS 26.4, macOS Sequoia 15.7.5, macOS Tahoe 26.4, tvOS 26.4, visionOS 26.4, watchOS 26.4. An app may be able to leak sensitive kernel state.

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

This vulnerability allowed a malicious or compromised application to bypass authentication checks and leak sensitive kernel state information. The issue was addressed through improved authentication mechanisms in the affected Apple operating systems, preventing unauthorized access to kernel-level data.

MitigationUsers should update their devices to the fixed versions (iOS 18.7.7/26.4, iPadOS 18.7.7/26.4, macOS Sequoia 15.7.5/Tahoe 26.4, tvOS 26.4, visionOS 26.4, watchOS 26.4). Organizations should ensure mobile device management (MDM) policies enforce OS updates and review any custom applications that interact with system APIs.

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 the device operating system version
    On iOS/iPadOS: Settings > General > About; On macOS: System Settings > General > About or run 'sw_vers'; On tvOS/watchOS/visionOS: Settings > General > About
    Affected if The installed version is less than 18.7.7 (for iOS/iPadOS), less than 15.7.5 or between 26.0 and 26.3 (for macOS), or less than 26.4 (for tvOS/watchOS/visionOS)
  2. Verify MDM or update management status
    For managed devices, check the MDM console to confirm whether device compliance policies are enforced and OS update installations are being blocked or delayed
    Affected if The device is not receiving OS updates due to delayed rollout policies, skipped updates, or MDM configuration that defers security patches
  3. Review installed applications for untrusted sources
    Check the device for applications installed outside of the official App Store (iOS/iPadOS) or not signed by a known developer (macOS), as these could be the malicious vectors described in the CVE
    Affected if Applications from untrusted or unknown developers are installed, particularly if they request system-level or kernel access permissions

The device is affected if it runs an OS version below the fixed releases (iOS/iPadOS 18.7.7/26.4, macOS 15.7.5/26.4, tvOS/watchOS/visionOS 26.4) and has untrusted applications that could exploit the authentication bypass to leak kernel state information.

Interim mitigation

Users should update their devices to the fixed versions (iOS 18.7.7/26.4, iPadOS 18.7.7/26.4, macOS Sequoia 15.7.5/Tahoe 26.4, tvOS 26.4, visionOS 26.4, watchOS 26.4). Organizations should ensure mobile device management (MDM) policies enforce OS updates and review any custom applications that interact with system APIs.

Recommended fix High confidence

iOS 18.7.7 or iOS 26.4 (iPhone); iPadOS 18.7.7 or iPadOS 26.4 (iPad); macOS Sequoia 15.7.5 or macOS Tahoe 26.4 (Mac); tvOS 26.4 (Apple TV); visionOS 26.4 (Vision Pro); watchOS 26.4 (Apple Watch)

  1. Identify the affected Apple device (iPhone, iPad, Mac, Apple TV, Vision Pro, or Apple Watch)
  2. Check the current OS version on the device in Settings > General > About (iOS/iPadOS) or System Settings > General > About (macOS)
  3. For iPhone/iPad: Upgrade to iOS 18.7.7 or iOS 26.4 / iPadOS 18.7.7 or iPadOS 26.4 depending on which major version line the device is on
  4. For Mac: Upgrade to macOS Sequoia 15.7.5 or macOS Tahoe 26.4 depending on which major version is installed
  5. For Apple TV: Upgrade to tvOS 26.4
  6. For Vision Pro: Upgrade to visionOS 26.4
  7. For Apple Watch: Upgrade to watchOS 26.4
  8. Install the update via Settings > General > Software Update (iOS/iPadOS/watchOS/tvOS/visionOS) or System Settings > General > Software Update (macOS)
Caveat Standard OS update risks apply; verify app compatibility after upgrading
