存在數據偽造問題漏洞，該漏洞源于在默認Open vSwitch防火墻規則中發現了一個缺陷，攻擊者可通過發送精心設計的數據包，任何控制連接到虛擬交換機的服務器實例的人都可以模擬網絡上其他系統的IPv6地址，從而導致拒絕服務。 CVE-2022-3277 OpenStack是一個云平臺管理項目。OpenStack openstack-neutron存在安全漏洞，該漏洞源于其資源消耗不受控允許遠程身份驗證用戶查詢無效項目的安全組列表。該操作會創建不受用戶配額約束的資源。如果惡意用戶提交大量請求，可能會導致拒絕服務。 CVE-2021-40085 OpenStack是一個云平臺管理項目。Neutron是其中的一個提供了網絡即服務（NaaS）的網絡組件，它能夠在OpenStack服務之間創建網絡、向網格中接入網絡設備等。OpenStack Neutron 存在安全漏洞，該漏洞源于軟件中對于extra_dhcp_opts的值缺乏有效的驗證和過濾，攻擊者通過提供特制的值可以對dnsmasq進程進行任意配置 CVE-2021-40797 OpenStack是一個云平臺管理項目。OpenStack Neutron存在安全漏洞，攻擊者可以利用該漏洞進行拒絕服務攻擊。 CVE-2021-38598 netfilter是一款使用在Linux系統中的數據包過濾框架。Netfilter 存在安全漏洞，攻擊者可利用該漏洞導致拒絕服務。 2. 受影響的操作系統及軟件包 ·銀河麒麟桌面操作系統V10 SP1 2403、銀河麒麟桌面操作系統V10
