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 · uneditedThe issue was addressed with improved checks. This issue is fixed in iOS 18.4 and iPadOS 18.4, iPadOS 17.7.6, macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5, tvOS 18.4, visionOS 2.4, watchOS 11.4. An app may be able to modify protected parts of the file system.
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 vulnerability in Apple's file system protection mechanisms allowed a malicious application to modify protected parts of the file system that should be restricted. The fix involved implementing improved checks to enforce proper file system access controls.

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.
-
Check macOS versionRun 'sw_vers -productVersion' in Terminal to get the exact macOS version numberAffected if The version is 13.0 to 13.7.4, 14.0 to 14.7.4, or 15.0 to 15.3 (falls within the vulnerable ranges)
-
Check iPadOS versionGo to Settings > General > About on the iPad to view the iPadOS versionAffected if The version is earlier than 17.7.6 (falls within the vulnerable range)
-
Verify System Integrity Protection status on macOSRun 'csrutil status' in Terminal. SIP is a core file system protection that, if disabled, could leave the system vulnerable to the bypass described in this CVEAffected if SIP is reported as disabled (this indicates the protection mechanism is not active)
-
Check for unauthorized file system modificationsRun 'ls -lO /System/Library/Sandbox/DefaultSystemPolicy 2>/dev/null' to inspect the root system directory for any unexpected permission changes or modifications to protected system filesAffected if There are unexpected changes to system file permissions or ownership in protected directories
You are affected if your macOS version is 13.0-13.7.4, 14.0-14.7.4, or 15.0-15.3, or your iPadOS version is before 17.7.6, and SIP (on macOS) is disabled or shows signs of bypass
