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 memory handling. This issue is fixed in iOS 17.4 and iPadOS 17.4, macOS Monterey 12.7.4, macOS Sonoma 14.4, macOS Ventura 13.6.5, tvOS 17.4. 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

Memory handling vulnerability in Apple kernel allows a malicious application to escalate privileges and execute arbitrary code with kernel-level access. This is a local privilege escalation (LPE) flaw where an app can break out of its sandbox to gain kernel privileges.

MitigationApply vendor-supplied OS updates: iOS 17.4+, iPadOS 17.4+, macOS Monterey 12.7.4+, macOS Sonoma 14.4+, macOS Ventura 13.6.5+, tvOS 17.4+. For enterprise environments, test and deploy via MDM.

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 iOS version on iPhone
    Open Settings > General > About, or run 'idevicesyslog' via macOS with connected device, or query via MDM enrollment status
    Affected if iOS version is below 17.4 (e.g., 17.3.x or earlier)
  2. Check iPadOS version on iPad
    Open Settings > General > About, or run 'idevicesyslog' via macOS with connected device, or query via MDM enrollment status
    Affected if iPadOS version is below 17.4 (e.g., 17.3.x or earlier)
  3. Check macOS version
    Run 'sw_vers -productVersion' in Terminal, or check System Settings > About This Mac > System Report
    Affected if Version is 12.0.0 through 12.7.4, 13.0 through 13.6.5, or 14.0 through 14.4 (any version in the vulnerable ranges)
  4. Check tvOS version
    Navigate to Settings > General > About on Apple TV, or query via MDM if enrolled in Apple TV management
    Affected if tvOS version is below 17.4 (e.g., 17.3.x or earlier)

The environment is affected if any Apple device runs an OS version within the vulnerable ranges: iOS/iPadOS/tvOS below 17.4, or macOS 12.0.0-12.7.4, 13.0-13.6.5, or 14.0-14.4.

Interim mitigation

Apply vendor-supplied OS updates: iOS 17.4+, iPadOS 17.4+, macOS Monterey 12.7.4+, macOS Sonoma 14.4+, macOS Ventura 13.6.5+, tvOS 17.4+. For enterprise environments, test and deploy via MDM.

Recommended fix High confidence

iOS 17.4+, iPadOS 17.4+, macOS 12.7.4+, macOS 13.6.5+, macOS 14.4+, tvOS 17.4+ (depending on product and current version)

  1. Identify the device type (iPhone, iPad, Mac, or Apple TV)
  2. Check the current OS version in Settings > General > About (iOS/iPadOS/tvOS) or System Settings > General > About (macOS)
  3. For iPhone or iPad: Upgrade to iOS 17.4 or iPadOS 17.4 or later
  4. For Mac running Monterey: Upgrade to macOS 12.7.4 or later
  5. For Mac running Ventura: Upgrade to macOS 13.6.5 or later
  6. For Mac running Sonoma: Upgrade to macOS 14.4 or later
  7. For Apple TV: Upgrade to tvOS 17.4 or later
  8. Install the update via Settings > General > Software Update (iOS/iPadOS/tvOS) or System Settings > General > Software Update (macOS)
Caveat Standard OS update; ensure backup of critical data before updating; some older apps may not be compatible with new OS versions
