We’re announcing two new Kubernetes releases in Thalassa Cloud: v1.34.2-0 and v1.33.6-0. These releases include security fixes that address high-severity vulnerabilities in runc, along with important component updates and stability improvements.
Critical Security Fixes Both releases include runc 1.3.3, which fixes three high-severity security vulnerabilities:
CVE-2025-31133 CVE-2025-52565 CVE-2025-52881 These vulnerabilities could allow full container breakouts by bypassing runc’s restrictions for writing to arbitrary /proc files. We recommend upgrading your clusters to these versions as soon as possible to mitigate these security risks.
