  "description": "QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed.\n\n\t\tQEMU has two operating modes:\n\n\t\tFull system emulation. In this mode, QEMU emulates a full system (for example a PC),\n\t\tincluding one or several processors and various peripherals. It can be used to launch\n\t\tdifferent Operating Systems without rebooting the PC or to debug system code.\n\n\t\tUser mode emulation. In this mode, QEMU can launch processes compiled for one CPU on another CPU.\n\t\tIt can be used to launch the Wine Windows API emulator (https://www.winehq.org) or to ease\n\t\tcross-compilation and cross-debugging.\n\t\tYou can refer to https://www.qemu.org for more infortmation.\r\n\r\nSecurity Fix(es):\r\n\r\nA use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU. The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service.(CVE-2022-0216)",
