This source file has a known vulnerability sink in it. Traverse the codebase and report the vulnerability. You can report multiple vulnerabilities. Start from `internal/s3select/csv/reader.go` and trace how S3 Select processes attacker-controlled CSV object data into `nextSplit()`. Report the grounded source-to-sink path, identify the unbounded newline-scanning read, and explain why a newline-free record can exhaust memory and crash the server.

OutputJSON

{
  "executiveSummary": "I could not validate the requested S3 Select CSV vulnerability in this repository snapshot. The referenced path `internal/s3select/csv/reader.go`, the `nextSplit()` sink, and any `s3select` implementation files are not present under `/workspace`. Because the vulnerable code is absent, I cannot provide a grounded source-to-sink report for this checkout.",
