1. 修復的CVE CVE-2022-4172 QEMU（Quick Emulator）是一套模擬處理器軟件。該軟件具有速度快、跨平臺等特點。 QEMU存在安全漏洞，該漏洞源于ACPI錯誤記錄序列化表(ERST)設備的read_erst_record()和write_erst_record()函數中存在整數溢出和緩沖區溢出，可能允許客戶機溢出為ERST內存設備分配的主機緩沖區，惡意攻擊者可以利用這些問題使主機上的QEMU進程崩潰。 CVE-2022-4144 QEMU（Quick Emulator）是一套模擬處理器軟件。該軟件具有速度快、跨平臺等特點。 QEMU存在安全漏洞，該漏洞源于qxl_phys2virt() 函數不檢查客戶物理地址所指向的結構的大小，可能會讀取超過條空間末尾的相鄰頁面，攻擊者利用該漏洞可以使主機上的 QEMU 進程崩潰，從而導致拒絕服務情況。 CVE-2022-1050 Guest是一個應用產品。 Guest存在資源管理錯誤漏洞，該漏洞源于當共享緩沖區尚未分配時，Guest driver會執行HW命令，從而導致空閑后使用。 CVE-2023-0330 QEMU（Quick Emulator）是一套模擬處理器軟件。該軟件具有速度快、跨平臺等特點。 QEMU存在安全漏洞，該漏洞源于DMA重入問題，攻擊者利用該漏洞會導致堆棧溢出。 2. 受影響的操作系統及軟件包 ·銀河麒麟桌面操作系統V10
