GHSA-g5p6-327m-3fxx Talos Linux ships runc vulnerable to the escape to the host attack

• Go github.com/siderolabs/talos: >= 1.6.0, < 1.6.4 → fixed in 1.6.4 • Go github.com/siderolabs/talos: < 1.5.6 → fixed in 1.5.6

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.
