pitrou opened a new issue, #49837:
URL: https://github.com/apache/arrow/issues/49837

   ### Describe the bug, including details regarding any error messages, 
version, and platform.
   
   `DeltaLengthByteArrayDecoder::DecodeArrow` and 
`DeltaByteArrayDecoder::DecodeArrow` both allocate a temporary `std::vector` 
for the entire range of decoded values.
   This generates out-of-memory failures in the Parquet encoding fuzzer as this 
unbounded allocation bypasses the custom fuzzing memory pool.
