This issue is fixed in iOS 16.7.9 and iPadOS 16.7.9, iOS 17.6 and iPadOS 17.6, macOS Monterey 12.7.6, macOS Sonoma 14.6, macOS Ventura 13.6.8, tvOS 17.6, visionOS 1.3, watchOS 10.6. Processing a maliciously crafted file may lead to 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 · high confidence

This is an out-of-bounds read vulnerability in multiple Apple operating systems. The vulnerability exists in file processing functionality where insufficient input validation allows a maliciously crafted file to trigger an out-of-bounds memory read, causing unexpected application termination (denial of service).

MitigationApply the vendor-supplied patches: iOS 16.7.9/17.6, iPadOS 16.7.9/17.6, macOS Monterey 12.7.6/Ventura 13.6.8/Sonoma 14.6, tvOS 17.6, visionOS 1.3, or watchOS 10.6 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. Check iOS version on iPhone or iPad
    Go to Settings > General > About and note the version number displayed next to 'Version'
    Affected if The version is below 16.7.9, or is 17.0 through 17.5 (any version >= 17.0 but < 17.6)
  2. Check iPadOS version
    Go to Settings > General > About and note the version number displayed next to 'Version'
    Affected if The version is below 16.7.9, or is 17.0 through 17.5 (any version >= 17.0 but < 17.6)
  3. Check macOS version
    Click the Apple menu > About This Mac and note the version number (for example 14.5, 13.6.7, 12.7.5)

Interim mitigation

Apply the vendor-supplied patches: iOS 16.7.9/17.6, iPadOS 16.7.9/17.6, macOS Monterey 12.7.6/Ventura 13.6.8/Sonoma 14.6, tvOS 17.6, visionOS 1.3, or watchOS 10.6 as appropriate for affected devices.

Recommended fix High confidence

Upgrade to iOS 16.7.9 or iPadOS 16.7.9 (iOS 17.6/iPadOS 17.6 for newer devices), macOS Monterey 12.7.6 / Ventura 13.6.8 / Sonoma 14.4 (or 14.6), tvOS 17.6, visionOS 1.3, or watchOS 10.6 depending on current device and OS version

  1. Check current device OS version in Settings > General > About (iOS/iPadOS/watchOS) or System Settings > About (macOS/tvOS/visionOS)
  2. Backup device data before updating
  3. Connect device to power and Wi-Fi
  4. For iOS/iPadOS: Go to Settings > General > Software Update and install the available update (16.7.9 for older devices, 17.6 for newer)
  5. For macOS: Go to System Settings > General > Software Update and install the appropriate update (12.7.6, 13.6.8, or 14.4/14.6)
  6. For tvOS: Go to Settings > General > About > Software Update
  7. For watchOS: Go to Settings > General > Software Update on paired iPhone Watch app
  8. For visionOS: Go to Settings > General > Software Update
Caveat Standard OS update considerations: ensure app compatibility, backup data before updating, and ensure sufficient battery/power during update process
