NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm-docs package and not the qemu-kvm-docs package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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.
