This flaw allows a malicious privileged user within the guest to crash the QEMU process on the host, resulting in a denial of service.
The flaw occurs while processing repeated messages to cancel the current SCSI request via the lsi_do_msgout function. (CVE-2021-4207) - A use-after-free vulnerability was found in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU.

A malicious privileged guest user could use this flaw to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process. A double fetch of guest controlled values `cursor->header.width` and `cursor->header.height` can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. (CVE-2021-4206) - A flaw was found in the QXL display device emulation in QEMU. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. A flaw was found in the QXL display device emulation in QEMU. Description The remote Oracle Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-9862 advisory. Synopsis The remote Oracle Linux host is missing one or more security updates.
