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 17.5 and iPadOS 17.5, tvOS 17.5, visionOS 1.2, watchOS 10.5. 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

This is a kernel privilege escalation vulnerability in multiple Apple operating systems (iOS 17.5, iPadOS 17.5, tvOS 17.5, visionOS 1.2, watchOS 10.5). The vulnerability stems from improper memory handling that allows a malicious application to escalate from user-level privileges to kernel-level (root) privileges, potentially enabling arbitrary code execution with full system control.

MitigationUpdate all affected Apple devices (iPhones, iPads, Apple TV, Vision Pro, Apple Watch) to iOS 17.5/iPadOS 17.5, tvOS 17.5, visionOS 1.2, or watchOS 10.5 or later to remediate this kernel privilege escalation vulnerability.

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 iPhone iOS version
    Go to Settings > General > About on the iPhone and note the version number under 'Version'
    Affected if Version is lower than 17.5 (for example, 17.4.1 or earlier)
  2. Check iPad iPadOS version
    Go to Settings > General > About on the iPad and note the version number under 'Version'
    Affected if Version is lower than 17.5 (for example, 17.4.1 or earlier)
  3. Check Apple TV tvOS version
    Go to Settings > General > About > Version on Apple TV
    Affected if Version is lower than 17.5 (for example, 17.4.1 or earlier)
  4. Check Vision Pro visionOS version
    Go to Settings > General > About on Vision Pro and note the version number under 'Version'
    Affected if Version is lower than 1.2 (for example, 1.1.x or earlier)
  5. Check Apple Watch watchOS version
    Open the Watch app on paired iPhone, go to My Watch > General > About and note the version, or go to Settings > General > About on the Watch itself
    Affected if Version is lower than 10.5 (for example, 10.4 or earlier)

If any Apple device runs an OS version below the minimum fixed version (iOS/iPadOS/tvOS 17.5, visionOS 1.2, or watchOS 10.5), the device is vulnerable to kernel privilege escalation.

Upgrade available Upgrade to 1.2 / 17.5 or later
Fixed in 1.217.5
Interim mitigation

Update all affected Apple devices (iPhones, iPads, Apple TV, Vision Pro, Apple Watch) to iOS 17.5/iPadOS 17.5, tvOS 17.5, visionOS 1.2, or watchOS 10.5 or later to remediate this kernel privilege escalation vulnerability.

Recommended fix High confidence

iOS 17.5 / iPadOS 17.5 / tvOS 17.5 / visionOS 1.2 / watchOS 10.5 (depending on device type)

  1. 1. Identify the Apple device model and current iOS/iPadOS/tvOS/visionOS/watchOS version by going to Settings > General > About
  2. 2. Determine if the device is running a version lower than the fixed release for your device (iOS 17.5/iPadOS 17.5, tvOS 17.5, visionOS 1.2, or watchOS 10.5)
  3. 3. Connect the device to power and Wi-Fi before updating
  4. 4. Back up your device data using iCloud or Finder/iTunes as a precaution
  5. 5. Install the update by navigating to Settings > General > Software Update and selecting 'Update'
  6. 6. After installation, verify the device is now running the fixed version (iOS 17.5, iPadOS 17.5, tvOS 17.5, visionOS 1.2, or watchOS 10.5)
Caveat Standard minor release update risks apply (rare post-update bugs possible); ensure backup before updating
