Descriptions

A Red Hat only CVE-2020-12352 regression issue was found in the way the Linux kernel's Bluetooth stack implementation handled the initialization of stack memory when handling certain AMP packets. This flaw allows a remote attacker in an adjacent range to leak small portions of stack memory on the system by sending specially crafted AMP packets. The highest threat from this vulnerability is to data confidentiality.

Se encontró un problema de regresión CVE-2020-12352 solo de Red Hat en la manera en que la implementación de la pila de Bluetooth del kernel de Linux manejaba la inicialización de la memoria de la pila al manejar determinados paquetes AMP. Este fallo permite a un atacante remoto en un rango adyacente filtrar pequeñas porciones de memoria de la pila en el sistema mediante el envío de paquetes AMP especialmente diseñados. La mayor amenaza de esta vulnerabilidad es la confidencialidad de los datos
