Local root privilege escalation
Published Nov 4, 2025 · Updated Nov 4, 2025
Incorrect authorization in Apple macOS before 15.7.2 and before 26.1 allows local users to gain root privileges through a malicious app. The DiskArbitration component applies insufficient permission restrictions, but Apple has not disclosed the affected operation or input path. Successful exploitation requires local code execution as a low-privileged user and results in full root-level control of the host.
