Summary
### Impact Snyk has discovered a vulnerability in all versions of runc <=1.1.11, as used by the Docker engine, along with other containerization technologies such as Kubernetes. Exploitation of this issue can result in container escape to the underlying host OS, either through executing a malicious image or building an image using a malicious Dockerfile or upstream image (i.e., when using FROM). This issue has been assigned the CVE-2024-21626. ### Patches `runc` runtime was updated to 1.1.12 in Talos v1.5.6 and v1.6.4. ### Workarounds Inspect the workloads running on the cluster to make sure they are not trying to exploit the vulnerability. ### References * [CVE-2024-21626](https://github.com/opencontainers/runc/security/advisories/GHSA-xr7r-f8xq-vfvv) * [Vulnerability: runc process.cwd and leaked fds container breakout](https://snyk.io/blog/cve-2024-21626-runc-process-cwd-container-breakout/)
