A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short frames was dropped from individual network devices and moved to the net core code. The issue stems from the device's receive code still being able to process a short frame in loopback mode. This could lead to a buffer overrun in the e1000_receive_iov() function via the loopback code path. A malicious guest user could use this vulnerability to crash the QEMU process on the host, resulting in a denial of service.

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

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.

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

  - A stack-based buffer overflow was found in the QEMU e1000 network device. The code for padding short     frames was dropped from individual network devices and moved to the net core code. The issue stems from     the device's receive code still being able to process a short frame in loopback mode. This could lead to a     buffer overrun in the e1000_receive_iov() function via the loopback code path. A malicious guest user     could use this vulnerability to crash the QEMU process on the host, resulting in a denial of service.
    (CVE-2025-12464)

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