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
An integer overflow was addressed by adopting 64-bit timestamps. This issue is fixed in iOS 18.7.3 and iPadOS 18.7.3, iOS 26.2 and iPadOS 26.2, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, watchOS 26.2. An app may be able to gain root privileges.

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

An integer overflow vulnerability in timestamp handling (32-bit timestamp overflow) in multiple Apple operating systems allows a malicious application to potentially gain root privileges. The vulnerability was addressed by implementing 64-bit timestamps.

MitigationApply the available Apple security updates (iOS 18.7.3/26.2, iPadOS 18.7.3/26.2, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, watchOS 26.2) to all 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. Check installed macOS version
    Open Terminal and run: `sw_vers -productVersion`
    Affected if The version returned is less than 14.8.3, or is 15.0 through 15.7.2 (including point releases within that range)
  2. Confirm macOS release name
    Run `sw_vers -productVersionExtra` or check System Settings > About to see if the system is macOS Sonoma (14.x) or macOS Sequoia (15.x)
    Affected if The system runs macOS Sonoma below 14.8.3 or macOS Sequoia between 15.0 and 15.7.2

You are affected if your macOS version is any build lower than 14.8.3 (Sonoma) or any build from 15.0 up to but not including 15.7.3 (Sequoia), as these versions still use 32-bit timestamps that can overflow to grant root privileges to malicious applications.

Interim mitigation

Apply the available Apple security updates (iOS 18.7.3/26.2, iPadOS 18.7.3/26.2, macOS Sequoia 15.7.3, macOS Sonoma 14.8.3, macOS Tahoe 26.2, tvOS 26.2, visionOS 26.2, watchOS 26.2) to all affected devices.

Recommended fix High confidence

macOS Sonoma 14.8.3 or macOS Sequoia 15.7.3

  1. Check the current macOS version by clicking the Apple menu and selecting About This Mac
  2. Identify whether you are running macOS Sonoma (14.x) or macOS Sequoia (15.x)
  3. For macOS Sonoma (14.x) users: Upgrade to macOS Sonoma 14.8.3 or later via System Settings > Software Update
  4. For macOS Sequoia (15.x) users: Upgrade to macOS Sequoia 15.7.3 or later via System Settings > Software Update
  5. After updating, verify the security update was applied by checking About This Mac > More Info > System Report > Software > Installed Software
Caveat Standard macOS update risks apply - backup important data before upgrading; some legacy applications may be incompatible with newer macOS versions
