CVE-2024-36006
Estado: ModificadaMedia (5.5)—
Detalles técnicos trazas, registros y código del informe original
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mlxsw: espectro_acl_tcam: corrige el uso incorrecto de la API de lista. Tanto la función que migra todos los fragmentos dentro de una región como la función que migra todas las entradas dentro de un fragmento llaman a list_first_entry() en el respectivo listas sin verificar que las listas no estén vacías. Este es un uso incorrecto de la API, lo que genera la siguiente advertencia [1]. Para solucionarlo, regrese si las listas están vacías, ya que en este caso no hay nada que migrar.
