Summary

udisks2 security update

Details

The Udisks project provides a daemon, tools and libraries to access and manipulate disks, storage devices and technologies.

Security Fix(es):

A flaw was found in udisks2. A local attacker with an active console session can exploit insufficient authorization checking on the 'as-user' option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method. This allows the attacker to spoof the 'as-user' parameter, mounting filesystems on behalf of arbitrary users, including privileged accounts. This can lead to local privilege escalation through mount point injection and manipulation of the mount namespace visible to privileged users.(CVE-2026-7867)

Severity

7.8 (High)

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.
