CVE-2025-12464Source published Source updated
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. This CVE is rated as Moderate because the vulnerability is confined to the loopback interface. Furthermore, even though e1000 is common for legacy Operating Systems, the device is generally discouraged in modern virtualization deployments (where virtio-net is recommended). Red Hat…
