CVE-2023-32155

Tesla Model 3 bcmdhd Out-Of-Bounds Write Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected Tesla Model 3 vehicles. An attacker must first obtain the ability to execute code on the wifi subsystem in order to exploit this vulnerability. The specific flaw exists within the bcmdhd driver. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. . Was ZDI-CAN-20733.

Summary		(es) Vulnerabilidad de escalada de privilegios locales de escritura fuera de los límites del Tesla Model 3 bcmdhd. Esta vulnerabilidad permite a los atacantes locales escalar privilegios en los vehículos Tesla Model 3 afectados. Un atacante primero debe obtener la capacidad de ejecutar código en el subsistema wifi para poder explotar esta vulnerabilidad. La falla específica existe en el controlador bcmdhd. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar una escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto del kernel. Era ZDI-CAN-20733.
