Vulnerability from osv_openeuler – Published: 2022-02-19 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

cryptsetup security update

Details

cryptsetup is a utility used to conveniently set up disk encryption based on the DMCrypt kernel module.

Security Fix(es):

It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that medium.(CVE-2021-4122)

Severity

5.9 (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.
