According to the versions of the qemu packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    A flaw was found in QEMU. A specially crafted VMDK image could trigger an out-of-bounds read     vulnerability, potentially leading to a 12-byte leak of sensitive information or a denial of service     condition (DoS).(CVE-2026-2243)

    A flaw was found in the virtio-crypto device of QEMU. A malicious guest operating system can exploit a     missing length limit in the AKCIPHER path, leading to uncontrolled memory allocation. This can result in a     denial of service (DoS) on the host system by causing the QEMU process to terminate     unexpectedly.(CVE-2025-14876)

    A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a     handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-     free in the use of the channel. This can be abused by a malicious client with network access to the VNC     WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client     authentication.(CVE-2025-11234)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:3077 advisory.

    Kernel-based Virtual Machine (KVM) is a full virtualization solution for Linux on a variety of     architectures. The qemu-kvm packages provide the user-space component for running virtual machines that     use KVM.

    Security Fix(es):

    * qemu-kvm: VNC WebSocket handshake use-after-free (CVE-2025-11234)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8073-1 advisory.

    It was discovered that the UHCI controller implementation of QEMU could be brought into an invalid state.
    An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial     of service. (CVE-2024-8354)

    It was discovered that QEMU incorrectly handled memory during certain VNC operations. An remote attacker     could possibly use this issue to cause QEMU to crash, resulting in a denial of service, or possibly     execute arbitrary code. (CVE-2025-11234)

    It was discovered that the e1000 network device implementation of QEMU could be made to write out of     bounds. An attacker inside the guest could possibly use this issue to cause QEMU to crash, resulting in a     denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 24.04 LTS and     Ubuntu 25.10. (CVE-2025-12464)

    It was discovered that the virtio-crypto device implementation of QEMU did not limit the length of a     certain path input. An attacker inside the guest could possibly use this issue to cause QEMU to consume     large amount of memory, resulting in a denial of service. This issue only affected Ubuntu 24.04 LTS and     Ubuntu 25.10. (CVE-2025-14876)

    It was discovered that the KVM Xen guest support of QEMU could be made to read out of bounds. An attacker     inside the guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service.
    This issue only affected Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2026-0665)
