CVE-2024-31146 (GCVE-0-2024-31146)

Vulnerability from cvelistv5 – Published: 2024-09-25 10:31 – Updated: 2024-09-25 13:24

Title

PCI device pass-through with shared resources

Summary

When multiple devices share resources and one of them is to be passed through to a guest, security of the entire system and of respective guests individually cannot really be guaranteed without knowing internals of any of the involved guests. Therefore such a configuration cannot really be security-supported, yet making that explicit was so far missing. Resources the sharing of which is known to be problematic include, but are not limited to - - PCI Base Address Registers (BARs) of multiple devices mapping to the same page (4k on x86), - - INTx lines.

Detection rules are retrieved from Rulezet.

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.
