CVE-2024-36020
Estado: ModificadaMedia (5.5)—
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: i40e: se puede usar vf sin inicializar en esta función advertencia Para corregir la regresión introducida por el commit 52424f974bc5, que hace que los servidores se cuelguen con mucha dificultad para reproducir condiciones con restablecimientos de ejecución. El uso de dos fuentes para la información es la causa fundamental. En esta función, antes de la corrección, tocar v no significaba tocar el puntero vf. Pero el código usaba estas variables indistintamente, por lo que un vf obsoleto podría apuntar a un vf diferente o no intencionado. Elimine la variable "v" redundante e itere mediante un único puntero VF en toda la función para garantizar la validez del puntero VF.
