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 18.4 and iPadOS 18.4, iPadOS 17.7.6, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, watchOS 11.4. Processing a maliciously crafted font may result in the disclosure of process memory.

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

A memory handling vulnerability in Apple's font processing subsystem allows a maliciously crafted font file to leak process memory contents when processed by the victim. This information disclosure occurs due to improper memory management during font parsing.

MitigationApply the appropriate Apple security updates (iOS 18.4, iPadOS 17.7.6/18.4, macOS Sequoia 15.4, Sonoma 14.7.5, Ventura 13.7.5, tvOS 18.4, or watchOS 11.4) to all affected devices. Avoid opening untrusted font files from unknown sources.

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
    Go to Settings > General > About on the iPhone and note the iOS version number
    Affected if Version is less than 18.4, or version is 17.x and less than 17.7.6
  2. Check iPadOS version
    Go to Settings > General > About on the iPad and note the iPadOS version number
    Affected if Version is less than 17.7.6, or version is >= 18.0 and less than 18.4
  3. Check macOS version
    Click Apple menu > About This Mac and note the macOS version (Ventura 13.x, Sonoma 14.x, or Sequoia 15.x)
    Affected if Version is 13.0 to 13.7.4, 14.0 to 14.7.4, or 15.0 to 15.3
  4. Check tvOS version
    Go to Settings > General > About > Version on Apple TV
    Affected if Version is less than 18.4
  5. Identify font processing activity
    Review recently opened font files from untrusted sources, as the vulnerability triggers when processing a maliciously crafted font
    Affected if A vulnerable OS version is confirmed AND a font file from an untrusted source was processed

The environment is affected if the installed OS version falls within any of the affected ranges AND a maliciously crafted font file has been processed.

Interim mitigation

Apply the appropriate Apple security updates (iOS 18.4, iPadOS 17.7.6/18.4, macOS Sequoia 15.4, Sonoma 14.7.5, Ventura 13.7.5, tvOS 18.4, or watchOS 11.4) to all affected devices. Avoid opening untrusted font files from unknown sources.

Recommended fix High confidence

iOS 18.4, iPadOS 18.4, iPadOS 17.7.6, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4

  1. Identify the current installed version of the affected Apple operating system (iOS, iPadOS, macOS, or tvOS)
  2. Back up all important data on the device
  3. Connect the device to a power source and ensure stable internet connectivity
  4. For iOS/iPadOS: Open Settings > General > Software Update and install the available update
  5. For macOS: Open System Settings > General > Software Update and install the available update
  6. For tvOS: Go to Settings > System > Software Updates and install the available update
  7. Restart the device if prompted to complete the installation
  8. Verify the installed version matches the fixed release
Caveat Apple OS updates generally include compatibility changes; some legacy apps or configurations may require updates after upgrading
