Root privilege escalation via CoreStorage injection
Published Sep 8, 2021 · Updated Aug 3, 2024
Injection in CoreStorage in Apple macOS before 11.5 allows local users to gain root privileges through a malicious application. CoreStorage insufficiently validates data before passing it to an undisclosed downstream operation; Apple has not published the affected function, input, or injection syntax. Exploitation requires execution of a malicious application on the Mac, after which the process gains root privileges.
