CVE-2018-16880 (GCVE-0-2018-16880)

Vulnerability from cvelistv5 – Published: 2019-01-29 16:00 – Updated: 2024-08-05 10:32

Summary

A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.

Severity

MSRC_CVE-2018-16880

Vulnerability from csaf_microsoft - Published: 2019-01-02 00:00 - Updated: 2021-12-16 00:00

Summary

A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest under specific conditions can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.

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.
