En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:
RDMA/efa: Mantener los recursos de EQ activos mientras el IRQ está registrado
El manejador de interrupciones de finalización accede al estado de la EQ y al búfer DMA. Su IRQ se registró antes de que ese estado se inicializara, mientras que la liberación de recursos liberó el búfer antes de que free_irq() sincronizara el manejador.
Inicializar la EQ sin armarla, registrar el IRQ y, a continuación, armarla. Invertir el orden de los recursos durante la liberación liberando el IRQ antes de destruir la EQ.
