CVE-2026-19027: Out-of-bounds Read

The H5Znbitdecompressonebyte, H5Znbitdecompressonenooptype, and H5Znbitdecompressoneatomic functions in H5Znbit.c in HDF5 through 2.3.0 advance a read index into the compressed chunk buffer without bounding it against the buffer's actual size. This allows attackers to cause an out-of-bounds heap...

CVE-2026-19026

H5Zfilternbit in H5Znbit.c in HDF5 through 2.3.0 dereferences cdvalues0 through cdvalues4 without validating that cdvalues is non-NULL or that cdnelmts is at least 5, the fixed size of the filter's header. This allows attackers to cause a denial of service via a crafted HDF5 file that stores the...
