Linux Kernel Bluetooth CMTP Module Double Free Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the CMTP module. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. Was ZDI-CAN-11977.
Vulnerabilidad de escalada de privilegios gratuita doble del módulo CMTP Bluetooth del kernel de Linux. Esta vulnerabilidad permite a atacantes locales escalar privilegios en las instalaciones afectadas del kernel de Linux. Un atacante primero debe obtener la capacidad de ejecutar código con altos privilegios en el sistema de destino para poder explotar esta vulnerabilidad. La falla específica existe dentro del módulo CMTP. El problema surge de la falta de validación de la existencia de un objeto antes de realizar más operaciones libres sobre el objeto. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código en el contexto del kernel. Era ZDI-CAN-11977.
