**Leaky Vessels:** Multiple high-severity vulnerabilities in runC and Buildkit (including CVE-2024-21626 and three Buildkit flaws) can enable container escapes, host filesystem access, and potential privilege escalation; vendors (runC, Docker, AWS, Google Cloud, Ubuntu) have released fixes and advisories and there is currently no evidence of exploitation in the wild.
