7.1 highEPSS 0.4%

High (7.1) in katacontainers kata-containers. EPSS 0.4% chance of exploitation in the next 30 days.

An improper file permissions vulnerability affects Kata Containers prior to 1.11.5. When using a Kubernetes hostPath volume and mounting either a file or directory into a container as readonly, the file/directory is mounted as readOnly inside the container, but is still writable inside the guest. For a container breakout situation, a malicious guest can potentially modify or delete files/directories expected to be read-only.
