存在数据伪造问题漏洞，该漏洞源于在默认Open vSwitch防火墙规则中发现了一个缺陷，攻击者可通过发送精心设计的数据包，任何控制连接到虚拟交换机的服务器实例的人都可以模拟网络上其他系统的IPv6地址，从而导致拒绝服务。 CVE-2022-3277 OpenStack是一个云平台管理项目。OpenStack openstack-neutron存在安全漏洞，该漏洞源于其资源消耗不受控允许远程身份验证用户查询无效项目的安全组列表。该操作会创建不受用户配额约束的资源。如果恶意用户提交大量请求，可能会导致拒绝服务。 CVE-2021-40085 OpenStack是一个云平台管理项目。Neutron是其中的一个提供了网络即服务（NaaS）的网络组件，它能够在OpenStack服务之间创建网络、向网格中接入网络设备等。OpenStack Neutron 存在安全漏洞，该漏洞源于软件中对于extra_dhcp_opts的值缺乏有效的验证和过滤，攻击者通过提供特制的值可以对dnsmasq进程进行任意配置 CVE-2021-40797 OpenStack是一个云平台管理项目。OpenStack Neutron存在安全漏洞，攻击者可以利用该漏洞进行拒绝服务攻击。 CVE-2021-38598 netfilter是一款使用在Linux系统中的数据包过滤框架。Netfilter 存在安全漏洞，攻击者可利用该漏洞导致拒绝服务。 2. 受影响的操作系统及软件包 ·银河麒麟桌面操作系统V10 SP1 2403、银河麒麟桌面操作系统V10
