canonical — Vulnerabilities & Security Advisories 126

Browse all 126 CVE security advisories affecting canonical. AI-powered Chinese analysis, POCs, and references for each vulnerability.

Canonical Ltd. primarily develops and maintains Ubuntu, a widely deployed Linux distribution, alongside the OpenStack cloud infrastructure platform and the Snap package management system. Security audits reveal a significant volume of recorded vulnerabilities, currently totaling 107 CVEs, reflecting the extensive codebase and third-party dependencies inherent in these large-scale software ecosystems. Historically, the most prevalent vulnerability classes include remote code execution (RCE), cross-site scripting (XSS), and privilege escalation flaws, often stemming from improper input validation or insecure default configurations within associated services. While no single catastrophic incident has defined the company’s security history, the sheer number of disclosed issues highlights the challenges of maintaining rigorous patch cycles across diverse components. These findings underscore the necessity for continuous monitoring and timely updates for organizations relying on Canonical’s open-source technologies to mitigate potential exploitation risks.
