Descriptions

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix NULL-deref on non-serdev setup Qualcomm ROME controllers can be registered from the Bluetooth line
discipline and in this case the HCI UART serdev pointer is NULL. Add the missing sanity check to prevent a NULL-pointer dereference when
setup() is called for a non-serdev controller.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: qca: corrige NULL-deref en configuración sin serdev. Los controladores Qualcomm ROME se pueden registrar desde la disciplina de línea Bluetooth y en este caso el puntero HCI UART serdev es NULL. Agregue la verificación de sanidad que falta para evitar una desreferencia del puntero NULL cuando se llama a setup() para un controlador que no es serdev.
