CVE-2022-42430

Root code execution via wowlan_config use-after-free

Published Mar 29, 2023 · Updated Feb 14, 2025

Use-after-free in Tesla Model 3 Infotainment 2021.44.30 and 2022.12.22 allows local users to execute arbitrary code as root. The wowlan_config handler operates on an object without first validating that the object still exists, dereferencing freed memory. Exploitation requires existing privileged code execution on the vehicle, after which the attacker gains root-level control of the infotainment system.
