@Tembocs , Thanks for the detailed report and the reproducible example. I’m interested in investigating this issue and working on a fix. From the description, it looks like the reader trusts the declared block/message body length before confirming that the data is actually available, which can lead to an excessively large allocation for malformed input. I’d like to investigate both the file IPC path and the stream/message reader path mentioned in the report, and add regression tests to ensure malformed length values return an appropriate ArrowError rather than causing an allocation failure or process abort. If no one is already working on this, would it be okay for me to take it up? -- This is an automated message from the Apache Git Service.
