Local privilege escalation via PackageKit state confusion

Privilege escalation in PackageKit in Apple macOS allows local users to obtain elevated privileges through incorrect state handling. Apple identifies the defect only as a logic issue corrected through improved state management and has not disclosed the faulty transition, function, or attacker-controlled input. Execution of an application is required; a public demonstration used the flaw as a local privilege-escalation stage in a larger one-click compromise chain.
