Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An off-by-one error was found in QEMU's KVM Xen guest support. A malicious guest could use this flaw to     trigger out-of-bounds heap accesses in the QEMU process via the emulated Xen physdev hypercall interface,     leading to a denial of service or potential memory corruption. (CVE-2026-0665)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:0662-1 advisory.

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.
