CVE-2017-13906

Privilege escalation via IOAcceleratorFamily memory corruption

Published Dec 23, 2021 · Updated Aug 5, 2024

Memory corruption in IOAcceleratorFamily in Apple macOS Sierra 10.12.6 allows local users to elevate privileges through a malicious app. The published advisory says IOAcceleratorFamily mishandles memory, but Apple has not disclosed the specific operation or attacker-controlled input. Execution of a malicious local application and user interaction are required; successful exploitation raises that application's privileges.
