## What's Changed `Lz4CompressionCodec.doDecompress` sizes the output buffer to the bytes it actually decompressed, but sets `writerIndex` to the length taken from the untrusted 8-byte prefix. A buffer whose prefix claims more than the real output leaves the returned `ArrowBuf` with a `writerIndex` past its capacity, and consumers then read off-heap memory beyond the allocation. This adds the actual-vs-claimed length check the ZSTD codec already does, so a mismatch throws instead of producing an over-long buffer.
