Name of the Vulnerable Software and Affected Versions Kubernetes CRI-O versions prior to 1.9

Description The issue is related to a Privilege Context Switching Error in the handling of ambient capabilities, which can result in containers running with elevated privileges. This allows users to have abilities they should not have. The attack is exploitable via container execution.

Recommendations For versions prior to 1.9, update to version 1.9 or later to resolve the issue. As a temporary workaround, consider restricting the execution of containers to minimize the risk of exploitation.
