AI-suggested

A fix is available and has been released in Ubuntu package versions 2.6.1-2ubuntu0.5 and 2.7.4-1ubuntu0.1. Users should update libexpat to these or later versions to remediate the vulnerability. Standard system updates on supported Ubuntu releases will apply the necessary patches. No additional mitigation steps are required beyond applying the official updates.

Description

A denial of service vulnerability exists in libexpat before version 2.8.1 due to inefficient attribute name collision checks. This flaw allows an attacker to cause excessive resource consumption by processing moderately sized crafted XML documents, leading to a denial of service condition. The issue affects multiple Ubuntu package versions and has been assigned CVE-2026-45186 with a high severity rating.
