Google.golang.org/grpc v1.82.1 shipped with three security fixes, and Kubernetes is patching it everywhere at once: externaljwt, endpointslice, kube-scheduler, and dynamic-resource-allocation all landed the update overnight.

The grpc-go update [1] [2] [3] [4] closes a critical DoS vector where HTTP/2 control frame floods could exhaust memory and CPU on gRPC servers. There is no v1.81.x backport, making this a forced upgrade for anyone on that line. The update also removes the GRPC_GO_EXPERIMENTAL_DISABLE_STRICT_PATH_CHECKING environment variable, which means any production configs using that flag need immediate attention before you deploy. In parallel, the scheduler landed In-Place Pod Resize preemption in alpha [5], giving your workload-conscious teams a new lever for managing resource-constrained clusters. DRA continues hardening itself with declarative validation for device metadata [6], additional DistinctAttribute test coverage [7], and critical fixes for shared device state management [8]. The documentation team synced Chinese language docs across tutorials and guides [9] [10] [11] [12], and security.txt moved to the proper well-known directory [13], ensuring compliance tooling can find your security contacts.
