Pull Request Overview

This update addresses several security vulnerabilities in the containerd dependency. However, the Go runtime version defined in the project configuration is currently susceptible to a high-severity x509 validation flaw (CVE-2026-27145). Furthermore, the PR does not include automated verification to ensure that these infrastructure changes do not impact container lifecycle stability or overall system compatibility.

About this PR

• The PR lacks tests or verification scenarios for a core dependency update. Ensuring container lifecycle operations remain functional is critical when updating core infrastructure components like containerd.

go.mod

_{line 3 🔴 HIGH RISK}
The Go standard library contains a high-severity security vulnerability (CVE-2026-27145) in the x509 certificate verification logic (x509.Certificate.VerifyHostname). This could allow an attacker to bypass hostname validation.

Test suggestions

• Verify that the project compiles and its dependencies are correctly resolved after the version upgrade.
• Run integration tests to ensure containerd compatibility with the current codebase, specifically checking container lifecycle operations.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify that the project compiles and its dependencies are correctly resolved after the version upgrade.
2. Run integration tests to ensure containerd compatibility with the current codebase, specifically checking container lifecycle operations.
