"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.");
