Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: smb: cliente: Se comprueba si la comprobación de añadir NULL en la página automount_fullpath contiene valores nulos en __build_path_from_dentry_optional_prefix cuando tcon->origin_fullpath no está configurado. Sin embargo, la comprobación no se encuentra disponible cuando sí lo está. Se ha añadido una comprobación para evitar una posible desreferencia de punteros NULL.
