security feature patch

Google Cloud has released updates for multiple versions of its Container Optimized OS (COS), enhancing the underlying infrastructure for containerized workloads. These updates include new Linux kernel versions, updated Docker and Containerd runtimes, and refreshed GPU drivers across various COS channels. Additionally, the releases incorporate a significant number of security fixes for critical Linux kernel vulnerabilities and enable the CONFIG_UDMABUF feature on x86_64 architectures. These changes improve system stability, performance, and overall security for users running containers on COS.
