Root privilege escalation via Core Services race
Published Jul 27, 2026 · Updated Jul 27, 2026
A race condition in Apple macOS Core Services allows local users to gain root privileges through a locally running app. Core Services performs unsafe state handling during concurrent operations, but Apple has not identified the affected function or shared state. A locally running app and a successful race are required; exploitation elevates that app to root and enables full control of the host.
