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 race condition was addressed with additional validation. This issue is fixed in iOS 18.2 and iPadOS 18.2, iPadOS 17.7.3, macOS Sequoia 15.2, macOS Sonoma 14.7.2, macOS Ventura 13.7.2, tvOS 18.2, visionOS 2.2, watchOS 11.2. An attacker may be able to create a read-only memory mapping that can be written to.

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 a race condition vulnerability in Apple's memory mapping subsystem that allows an attacker to create a writable mapping of read-only memory. The race condition occurs during memory mapping operations, potentially enabling memory corruption or local privilege escalation.

MitigationApply the vendor-supplied patches: update to iOS 18.2/iPadOS 18.2/17.7.3, macOS Sequoia 15.2/Sonoma 14.7.2/Ventura 13.7.2, tvOS 18.2, visionOS 2.2, or watchOS 11.2 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. Identify your Apple device and operating system
    Determine whether the device runs iOS, iPadOS, macOS, tvOS, visionOS, or watchOS. Use Settings > General > About on iOS/iPadOS, System Settings > About on macOS, or the Settings app on tvOS/visionOS/watchOS.
    Affected if The device runs any of the affected Apple operating systems listed in the CVE.
  2. Check iOS or iPadOS version
    On iPhone or iPad, go to Settings > General > About and note the Software Version. Compare the version number against the affected ranges: iOS < 18.2 or iPadOS < 17.7.3, or iPadOS >= 18.0 and < 18.2.
    Affected if The installed iOS version is below 18.2, or the installed iPadOS version is below 17.7.3 or between 18.0 and 18.2.
  3. Check macOS version
    On Mac, go to System Settings > About (or Apple menu > About This Mac) and note the version number. Compare against affected ranges: macOS Ventura < 13.7.2, macOS Sonoma >= 14.0 and < 14.7.2, or macOS Sequoia >= 15.0 and < 15.2.
    Affected if The installed macOS version is below 13.7.2, between 14.0 and 14.7.2, or between 15.0 and 15.2.
  4. Check tvOS, visionOS, or watchOS version
    On Apple TV, go to Settings > General > About. On Apple Vision Pro, go to Settings > General > About. On Apple Watch, open the Watch app on iPhone and go to My Watch > General > About. Note the version and compare: tvOS < 18.2, visionOS < 2.2, or watchOS < 11.2.
    Affected if The installed tvOS version is below 18.2, visionOS is below 2.2, or watchOS is below 11.2.

If the installed OS version falls within any of the affected ranges listed for the specific device type, the environment is vulnerable to this race condition flaw.

Upgrade available Upgrade to 2.2 / 11.2 / 13.7.2 or later
Fixed in 2.211.213.7.2
Interim mitigation

Apply the vendor-supplied patches: update to iOS 18.2/iPadOS 18.2/17.7.3, macOS Sequoia 15.2/Sonoma 14.7.2/Ventura 13.7.2, tvOS 18.2, visionOS 2.2, or watchOS 11.2 as appropriate for affected devices.

Recommended fix High confidence

Upgrade to iOS 18.2 / iPadOS 18.2 / iPadOS 17.7.3 / macOS Ventura 13.7.2 / macOS Sonoma 14.7.2 / macOS Sequoia 15.2 / tvOS 18.2 / visionOS 2.2 / watchOS 11.2 (depending on device type and desired version branch)

  1. Identify the specific Apple device and current operating system version
  2. For iPhone: Upgrade to iOS 18.2
  3. For iPad: Upgrade to iPadOS 18.2 (or iPadOS 17.7.3 if staying on iOS 17.x branch)
  4. For Mac: Upgrade to macOS Ventura 13.7.2, macOS Sonoma 14.7.2, or macOS Sequoia 15.2 depending on your hardware support
  5. For Apple TV: Upgrade to tvOS 18.2
  6. For Apple Vision Pro: Upgrade to visionOS 2.2
  7. For Apple Watch: Upgrade to watchOS 11.2
  8. Install the update via Settings > General > Software Update on iOS/iPadOS/watchOS/tvOS/visionOS, or System Settings > Software Update on macOS
Caveat Users on older hardware may not support the latest OS versions and may need to stay on the 17.x/13.x branch for continued support
