Root Cause Analysis
The vulnerability stems from missing device cgroup restrictions in container creation. The key patch adds updateDeviceCgroupForGuestRootfs() call in agentGRPC.CreateContainer, indicating this was the execution point where security controls were previously absent. The function signature matches the gRPC endpoint that would be invoked during container initialization, making it the primary vulnerable entry point visible in runtime traces.
