CVE-2026-6369 (GCVE-0-2026-6369)

Vulnerability from cvelistv5 – Published: 2026-04-20 13:38 – Updated: 2026-04-20 14:06

Title

Exposed Session Token in canonical-livepatch client snap

Summary

An improper access control vulnerability in the canonical-livepatch snap client prior to version 10.15.0 allows a local unprivileged user to obtain a sensitive, root-level authentication token by sending an unauthenticated request to the livepatchd.sock Unix domain socket. This vulnerability is exploitable on systems where an administrator has already enabled the Livepatch client with a valid Ubuntu Pro subscription. This token allows an attacker to access Livepatch services using the victim's credentials, as well as potentially cause issues to the Livepatch server.

Severity

This token allows an attacker to access Livepatch services using the victim\u0027s credentials, as well as potentially cause issues to the Livepatch server.",

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.
