CVE-2025-43244
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 · uneditedA race condition was addressed with improved state handling. This issue is fixed in macOS Sequoia 15.6, macOS Sonoma 14.7.7, macOS Ventura 13.7.7. An app may be able to cause unexpected system termination.
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 · moderate confidenceA race condition in macOS kernel state handling allows a local application to trigger an unexpected system termination (kernel panic). The vulnerability has a CVSS 9.8 rating due to the ease of exploitation and complete system impact.

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 macOS versionClick the Apple menu > About This Mac. Note the version number displayed (for example, 15.5, 14.6, 13.6). Alternatively, run 'sw_vers -productVersion' in Terminal.Affected if The version is less than 13.7.7, or falls between 14.0 and 14.7.6, or falls between 15.0 and 15.5.
-
Confirm build number matches OS releaseRun 'uname -r' in Terminal to see the kernel release, then cross-reference with the major version found in About This Mac to ensure they align.Affected if The kernel version does not match an unpatched release as listed in the affected version ranges.
-
Verify patch status via softwareupdateRun 'softwareupdate --list' in Terminal to check if any security updates are pending or have been installed.Affected if No security update corresponding to CVE-2025-43244 (or the equivalent macOS 15.6/14.7.7/13.7.7 update) appears in the list of installed updates.
A system is affected if it runs any macOS version below 13.7.7, between 14.0-14.7.6, or between 15.0-15.5, and has not received the corresponding security patch.
