high Nessus 插件 ID 281556
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- net/mlx5e不再克隆流 post 操作属性时该代码已克隆 mlx5e_clone_flow_attr_for_post_act() 中的 post 操作属性。在 mlx5e_tc_post_act_add() 中创建另一个副本是原始实现的错误残留。而是将 handle->attribute 分配给调用程序提供的 post_attr。请注意第二次克隆属性不仅造成资源消耗还会造成如下释放后使用的问题例如邻居更新代码中未正确更新第二个副本
