1. 修复的CVE CVE-2022-4172 QEMU（Quick Emulator）是一套模拟处理器软件。该软件具有速度快、跨平台等特点。 QEMU存在安全漏洞，该漏洞源于ACPI错误记录序列化表(ERST)设备的read_erst_record()和write_erst_record()函数中存在整数溢出和缓冲区溢出，可能允许客户机溢出为ERST内存设备分配的主机缓冲区，恶意攻击者可以利用这些问题使主机上的QEMU进程崩溃。 CVE-2022-4144 QEMU（Quick Emulator）是一套模拟处理器软件。该软件具有速度快、跨平台等特点。 QEMU存在安全漏洞，该漏洞源于qxl_phys2virt() 函数不检查客户物理地址所指向的结构的大小，可能会读取超过条空间末尾的相邻页面，攻击者利用该漏洞可以使主机上的 QEMU 进程崩溃，从而导致拒绝服务情况。 CVE-2022-1050 Guest是一个应用产品。 Guest存在资源管理错误漏洞，该漏洞源于当共享缓冲区尚未分配时，Guest driver会执行HW命令，从而导致空闲后使用。 CVE-2023-0330 QEMU（Quick Emulator）是一套模拟处理器软件。该软件具有速度快、跨平台等特点。 QEMU存在安全漏洞，该漏洞源于DMA重入问题，攻击者利用该漏洞会导致堆栈溢出。 2. 受影响的操作系统及软件包 ·银河麒麟桌面操作系统V10
