OESA-2024-2550 (CVE-2023-20584)

Vulnerability from osv_openeuler – Published: 2024-12-13 11:08 – Updated: 2026-08-06 11:08 – Source website

Summary

linux-firmware security update

Details

This package contains firmware images required by some devices.

Security Fix(es):

IOMMU improperly handles certain special address ranges with invalid device table entries (DTEs), which may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a loss of guest integrity.(CVE-2023-20584)

Incomplete system memory cleanup in SEV firmware could allow a privileged attacker to corrupt guest private memory, potentially resulting in a loss of data integrity.(CVE-2023-31356)

Severity

5.3 (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.
