nd_buf is used to buffer headers (for both the kernel dump itself and for EKCD) before the final call to netdump_dumper(), which flushes residual data in nd_buf. As a result, a small portion of the residual data would be corrupted. This manifests when kernel dump compression is enabled since both zstd and zlib detect the corruption during decompression.
