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
A denial-of-service issue was addressed with improved validation. This issue is fixed in iOS 18.7 and iPadOS 18.7, macOS Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26. An app may be able to cause a denial-of-service.

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

A denial-of-service vulnerability in Apple's iOS, iPadOS, and macOS operating systems was addressed through improved input validation. The issue allows a maliciously crafted app to potentially cause a system crash or unresponsiveness. The vulnerability is fixed in iOS 18.7/iPadOS 18.7, macOS Sequoia 15.7, macOS Sonoma 14.8, and macOS Tahoe 26.

MitigationApply the available OS updates (iOS 18.7, iPadOS 18.7, macOS Sequoia 15.7, macOS Sonoma 14.8, or macOS Tahoe 26) to all affected devices. Until patched, avoid installing apps from untrusted 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. Identify your device operating system
    Determine if the device runs iOS (iPhone), iPadOS (iPad), or macOS. On iOS/iPadOS, go to Settings > General > About. On macOS, click the Apple menu > About This Mac.
    Affected if The device runs any of the affected Apple operating systems
  2. Check iOS or iPadOS version
    On iOS/iPadOS, go to Settings > General > About and note the 'Software Version' number (for example, 18.6 or 18.7).
    Affected if The version is less than 18.7 (for example, 18.6, 18.5, or earlier)
  3. Check macOS version and build
    On macOS, click the Apple menu > About This Mac. Note the version number (such as 15.6, 15.7, 14.7, or 14.8) and the build number shown by clicking 'More Info'.
    Affected if The version is 14.0 through 14.7 (Sonoma) OR 15.0 through 15.6 (Sequoia)
  4. Confirm exploit trigger condition
    This vulnerability requires a maliciously crafted app to be installed on the device to trigger the denial-of-service condition.
    Affected if The device runs a vulnerable OS version AND has a malicious app installed or is likely to install apps from untrusted sources

You are affected if your iOS/iPadOS version is below 18.7, or your macOS version is between 14.0-14.7 or between 15.0-15.6, and a malicious app could be installed on the device.
