1. 修复的CVE CVE-2021-3631 Red Hat libvirt是一个用于实现Linux虚拟化功能的Linux API，它支持各种Hypervisor，包括Xen和KVM，以及QEMU和用于其他操作系统的一些虚拟产品。 Red Hat libvirt 存在安全漏洞，攻击者可以通过libvirt绕过限制，以提升他在主机系统上的权限。 CVE-2020-25637 Red Hat libvirt是一个用于实现Linux虚拟化功能的Linux API，它支持各种Hypervisor，包括Xen和KVM，以及QEMU和用于其他操作系统的一些虚拟产品。 Red Hat libvirt 资源管理错误漏洞。该漏洞源于网络系统或产品对系统资源（如内存、磁盘空间、文件等）的管理不当。 CVE-2021-4147 Red Hat libvirt是一个用于实现Linux虚拟化功能的Linux API，它支持各种Hypervisor，包括Xen和KVM，以及QEMU和用于其他操作系统的一些虚拟产品。 Red Hat libvirt 存在安全漏洞，攻击者可利用该漏洞触发主机系统上的拒绝服务。 CVE-2022-0897 Red Hat libvirt是一个用于实现Linux虚拟化功能的Linux API，它支持各种Hypervisor，包括Xen和KVM，以及QEMU和用于其他操作系统的一些虚拟产品。 libvirt nwfilter driver存在安全漏洞，该漏洞源于virNWFilterObjListNumOfNWFilters方法在迭代virNWFilterObj实例之前未能获取“driver->nwfilters”互斥锁，不能阻止另一个线程同时修改“driver->nwfilters”对象。攻击者利用该漏洞通过libvirt的API virConnectNumOfNWFilters使网络过滤器管理守护进程(libvirtd/virtnwfilterd)崩溃。 CVE-2021-3975 Red Hat libvirt是一个用于实现Linux虚拟化功能的Linux API，它支持各种Hypervisor，包括Xen和KVM，以及QEMU和用于其他操作系统的一些虚拟产品。 Red Hat libvirt 存在资源管理错误漏洞，该漏洞源于 VM 关闭期间的分段错误会导致 vdsm 挂起。 CVE-2021-3667 Red Hat libvirt是一个用于实现Linux虚拟化功能的Linux API，它支持各种Hypervisor，包括Xen和KVM，以及QEMU和用于其他操作系统的一些虚拟产品。 在libvirt的virStoragePoolLookupByTargetPath API中发现不正确的锁定问题。连接到ACL权限有限的读写套接字的客户端可能会使用此漏洞获取锁并阻止其他用户访问存储池/卷API，从而导致拒绝服务的情况。此漏洞的最大威胁是系统可用性。 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 x86_64 架构：
