The issue was addressed with improved bounds checks. This issue is fixed in iOS 18.2 and iPadOS 18.2, macOS Sequoia 15.2, tvOS 18.2, watchOS 11.2. An app may be able to corrupt coprocessor 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 corruption vulnerability in Apple operating systems allows a malicious application to corrupt coprocessor memory through improper bounds checking. The flaw affects iOS, iPadOS, macOS, tvOS, and watchOS, potentially enabling local privilege escalation or unexpected behavior.

MitigationApply vendor-supplied patches by updating affected devices to iOS 18.2/iPadOS 18.2, macOS Sequoia 15.2, tvOS 18.2, or watchOS 11.2 as appropriate.

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 Apple device and operating system
    Determine whether the device runs iOS, iPadOS, macOS, tvOS, or watchOS. For iOS/iPadOS, go to Settings > General > About. For macOS, go to System Settings > About This Mac. For tvOS, go to Settings > General > About. For watchOS, go to the Watch app on iPhone > General > About Watch.
    Affected if Any Apple device running one of the affected operating systems
  2. Check iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About and note the software version number displayed next to 'Version'.
    Affected if The version shown is below 18.2 (for example, 18.1.x, 18.0.x, or earlier)
  3. Check macOS version
    On Mac, go to System Settings > About This Mac and note the version number shown (for example, 15.1, 15.0, 14.x).
    Affected if The version shown is below 15.2 (for example, 15.1.x, 15.0.x, or earlier)
  4. Check tvOS version
    On Apple TV, go to Settings > General > About and note the tvOS version number displayed.
    Affected if The version shown is below 18.2 (for example, 18.1.x, 18.0.x, or earlier)
  5. Check watchOS version
    On Apple Watch, open the Watch app on paired iPhone, go to General > About, and note the watchOS version. Alternatively, on the watch go to Settings > General > About.
    Affected if The version shown is below 11.2 (for example, 11.1.x, 11.0.x, or earlier)

You are affected if your device runs any version of iOS, iPadOS, tvOS, or watchOS below 18.2, macOS below 15.2, or watchOS below 11.2.
