Security
A new vulnerability (CVE-2022-1786) has been discovered in the Linux kernel versions 5.10 and 5.11. This vulnerability allows an unprivileged user with local access to the cluster to achieve a full container breakout to root on the node. Only clusters that run Container-Optimized OS are affected. GKE Ubuntu versions use either version 5.4 or 5.15 of the kernel and are not affected. For more information, refer to the GCP-2022-017 security bulletin.
Changed
GKE Cost Allocation has been released for public preview. With GKE Cost
Allocation public preview, you will be able to see cost breakdowns in clusters
for namespaces, and pod labels for utilized CPU and MEM. For complete details,
