Sensitive data disclosure via incorrect Kernel check
Published Jul 27, 2026 · Updated Jul 27, 2026
Improper access control in the Kernel on macOS Sonoma before 14.8.8, Sequoia before 15.7.8, and Tahoe before 26.6 allows attackers to read user data. The Kernel performs an undisclosed incorrect check that lets a local app cross an access-control boundary; Apple has not identified the affected operation or sensitive data class. Exploitation requires local app execution and user interaction, and the published consequence is limited to disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <14.8.8
- Affected versionversion=0 <15.7.8
- Affected versionversion=0 <26.6
