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 memory corruption issue was addressed with improved lock state checking. This issue is fixed in iOS 18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1, tvOS 26.1, visionOS 26.1, watchOS 26.1. A malicious application may cause unexpected changes in memory shared between processes.

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

Memory corruption vulnerability in Apple operating systems involving improper lock state checking in inter-process shared memory handling. A malicious local application can manipulate shared memory between processes, potentially leading to arbitrary code execution or data corruption.

MitigationApply vendor-supplied security updates (iOS 18.7.2/26.1, iPadOS 18.7.2/26.1, macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe 26.1, tvOS 26.1, visionOS 26.1, watchOS 26.1) to all affected Apple 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
    Open Settings > General > About and note the version number (e.g., 18.7.1)
    Affected if Version is below 18.7.2 OR version equals 26.0
  2. Check iPadOS version on iPad
    Open Settings > General > About and note the version number
    Affected if Version is below 18.7.2 OR version equals 26.0
  3. Check macOS version on Mac
    Click Apple menu > About This Mac and note the version number (e.g., 15.6, 14.7)
    Affected if Version is 14.0 through 14.8.1 inclusive, OR 15.0 through 15.7.1 inclusive, OR equals 26.0
  4. Check tvOS version on Apple TV
    Go to Settings > General > About > Version
    Affected if Version is below 26.1
  5. Check visionOS version on Vision Pro
    Go to Settings > General > About > Version
    Affected if Version is below 26.1
  6. Check watchOS version on Apple Watch
    Open the Watch app on paired iPhone, go to General > About and note the version
    Affected if Version is below 26.1

Any device running an Apple operating system version that falls within the listed ranges is affected; the shared memory feature is a kernel-level component enabled by default, so no additional configuration check is needed.
