+  HDF5 2.0 returns values for them that the file does not hold:
+  - `cve_hdf5/cvefiles/cve-2025-2308.h5` `/Scale_offset_long_long_data_le`: scale-offset codes run past the end of the chunk: HDF5 2.0 reads past its buffer; libhdf5's develop branch refuses the chunk ("Buffer too short").
+  - `cve_hdf5/cvefiles/cve-2025-44904.h5` `/Scale_offset_float_data_le`: unfiltered chunks of 38 and 37 bytes for 48-byte chunks: HDF5 2.0 fills the rest with whatever its buffer held; libhdf5's develop branch refuses them ("incorrect chunk size returned from index for unfiltered chunk").
+  - `hdf5/test/testfiles/bad_nbit_parms_walk.h5` `/Nbit_int_data_le`: an N-Bit parameter list one value short: HDF5 2.0 reads past the list; libhdf5's own test (`test_filter_bad_params`, test/dsets.c) now requires the read to fail.
