Resource Exhaustion Affecting kubernetes-csi-node-driver-registrar-2.16 package, versions <2.16.0-r28
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Upgrade Wolfi kubernetes-csi-node-driver-registrar-2.16 to version 2.16.0-r28 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kubernetes-csi-node-driver-registrar-2.16 package and not the kubernetes-csi-node-driver-registrar-2.16 package as distributed by Wolfi.
See How to fix? for Wolfi relevant fixed versions and status.
gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, internal/transport/transport.go stores each fragmented HTTP/2 DATA frame as a separate recvMsg in recvBuffer, so millions of one-byte frames can consume disproportionate heap memory even when payload bytes remain within connection and stream flow-control windows. An unauthenticated remote attacker can use concurrent multiplexed streams to exhaust process memory and cause a runtime panic or out-of-memory termination. Receive-buffer compaction is enabled by default and can be controlled temporarily with GRPC_GO_EXPERIMENTAL_ENABLE_RECEIVE_BUFFER_COMPACTION. This issue is fixed in version 1.83.1.
