Root privilege escalation via missing entitlement checks
Published Sep 14, 2026 · Updated Sep 14, 2026
Privilege escalation in Bluetooth in Apple macOS before 27 allows local users to gain root privileges through a malicious app. The Bluetooth component accepts an app operation without the entitlement checks required to prevent privileged execution; Apple has not disclosed the affected request or code path. Execution of an app on an affected Mac is required, and successful exploitation grants root-level control rather than remote access.
