RHSA-2024_9136

Vulnerability from csaf_redhat - Published: 2024-11-12 09:14 - Updated: 2024-12-12 04:11

Summary

Red Hat Security Advisory: qemu-kvm security update

Severity

Moderate

Scope

3 vulnerabilities in this advisory, including CVE-2024-26327.

CVE-2024-26327

A flaw was found in the SR/IOV emulation support of QEMU. The register_vfs() function in hw/pci/pcie_sriov.c mishandled the situation where a guest writes NumVFs greater than TotalVFs, leading to a buffer overflow in VF (Virtual Function) implementations. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition.

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.
