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.
-
Determine installed macOS versionClick the Apple menu > About This Mac. The version number is displayed under the macOS name (e.g., 14.5, 13.6.7, 12.7.5). Alternatively, run 'sw_vers -productVersion' in Terminal.Affected if The version displayed is 12.7.5 or earlier, 13.6.7 or earlier, or 14.5 or earlier (meaning it is less than 12.7.6, 13.6.8, or 14.6 respectively)
-
Confirm version is within affected rangeCompare your installed version against the vulnerable ranges: macOS 12.0 to 12.7.5, macOS 13.0 to 13.6.7, and macOS 14.0 to 14.5. If your version matches any of these ranges, the system is potentially affected.Affected if The installed version falls within 12.0-12.7.5, 13.0-13.6.7, or 14.0-14.5
A user is affected if their macOS version is less than 12.7.6, 13.6.8, or 14.6, placing it within one of the vulnerable version ranges.
