CVE-2025-43290 Apple CVE debrief

Who should care

macOS system administrators, endpoint security teams, and organizations with managed Apple fleets should prioritize patching. The vulnerability could enable persistence mechanisms or system compromise if exploited by malicious software with local access.

Technical summary

This vulnerability stems from insufficient permission restrictions in macOS that could allow a malicious or compromised application to modify protected areas of the file system. The attack vector is local, requiring an application to execute on the target system. Apple's fix implements additional restrictions to prevent unauthorized modifications to protected file system locations. The cross-version patching (Sequoia, Sonoma, and Tahoe) indicates the underlying issue affected multiple macOS branches.

Defensive priority

Recommended defensive actions

• Apply the relevant security update: macOS Sequoia 15.7, macOS Sonoma 14.8, or macOS Tahoe 26
• Review application permissions and file system access controls on managed macOS endpoints
• Monitor for unusual file system modifications in protected directories on unpatched systems
• Validate that endpoint protection solutions detect attempts to modify protected system locations

Evidence notes

The CVE description confirms this is a permissions issue resolved through additional restrictions. Apple security update pages (HT201222 family) are the authoritative source for patch availability. Vendor identification as Apple is based on reference domain evidence with low confidence due to canonical source weakness; the vendor field requires review.
