Gatekeeper bypass via Kernel state-management flaw
Published Sep 14, 2026 · Updated Sep 14, 2026
A Kernel logic flaw in Apple macOS before 15.8, before 26.7, and before 27 allows local users to bypass Gatekeeper via a malicious application. The Kernel mishandles security-relevant state, but Apple has not disclosed the affected function, state transition, or input that triggers the incorrect decision. Execution of a malicious application is required; the bounded consequence is evasion of Gatekeeper trust checks, not a separately reported privilege gain.
