Vulnerability from github – Published: 2025-11-01 00:30 – Updated: 2026-05-06 18:30

Details

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.

Severity

6.2 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
