50/100CAUTION

TRUSTED

This image carries significant risk; production deployment is highly discouraged without strict compensating controls. An attacker with pod creation permissions could exploit CVE-2026-50195 to execute arbitrary code via a malicious checkpoint image, or use CVE-2026-53492 to bypass security controls via CDI device injection. Disabling CRI checkpoint import and CDI, if not needed, fully eliminates these vulnerabilities. Note that these vulnerabilities require non-default features (CRI checkpoint and CDI) to be enabled.

Scanning procedure

  1. Vulnerability scan
    Full CVE sweep across OS packages and app dependencies
  2. Exploitability check
    CVEs ranked by exploit probability (EPSS) and matched against CISA KEV
  3. Reachability analysis
    Symbol-level proof: is the vulnerable code even linked and callable in your binaries?
  4. Runtime verification
    Live-container probes: exposed endpoints, feature flags, real defaults
  5. Supply chain analysis
    Base-image lineage, package provenance and signatures — nothing slipped in unnoticed
  6. Hardening recommendations
    A hardened build plan — patch, remove unused packages, lock down the runtime — with parity tests proving nothing broke
