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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed macOS versionRun `sw_vers -productVersion` in Terminal or check System Settings > About This MacAffected if The version falls within any of the vulnerable ranges: 14.0-14.8.6 (Sonoma), 15.0-15.7.6 (Sequoia), or 26.0-26.4 (Tahoe)
-
Confirm macOS release nameRun `sw_vers -productVersionExtra` or check the marketing name in System Settings > About This MacAffected if The system is running Sonoma, Sequoia, or Tahoe within the affected version windows
-
Compare against fixed versionsCompare your exact version number to the security update thresholds: 14.8.7, 15.7.7, or 26.5Affected if Your installed version is lower than the fixed version for your respective macOS release
You are affected if your macOS version is Sonoma 14.x below 14.8.7, Sequoia 15.x below 15.7.7, or Tahoe 26.x below 26.5, as these versions contain the vulnerable code that allows modification of protected file system areas.
