CVE-2026-26199

A flaw was found in HDF5, a library used for managing large datasets. This vulnerability occurs when a specific function, H5Igetname, is called with an invalid size parameter, leading to a buffer underflow. An attacker could exploit this by providing specially crafted input, potentially causing t...

CVE-2026-26197

A flaw was found in HDF5, a high-performance library and file format specification. A remote attacker can exploit this vulnerability by providing a maliciously altered HDF5 file. If the file's array datatype has inconsistent size, element count, or element size, it can trigger an out-of-bounds...

DEBIAN-CVE-2026-26197

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If a file is corrupted such that an array datatype's size, the number of elements, and the element size are not in agreement it can trigger an out of bounds read. The array datatype stores the...

CVE-2026-26199

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If H5Igetname is invoked on a group id with 0 for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if H5Igetname is invoked in a way...

CVE-2026-26199

The CVE-2026-26199 entry describes a buffer underflow in HDF5 when calling H5Iget_name (and H5G_get_name) with a size of zero. Under conditions where an ID is queried with size forced to zero and there is significant data before the name buffer, the function may fail to place a null terminator, l...

CVE-2026-26199 Buffer underflow in `H5Iget_name `/`H5G_get_name` if size is zero

HDF5 is a high-performance library and a file format specification that implements the HDF5 data model. If H5Igetname is invoked on a group id with 0 for the size parameter, it will underflow when trying to place a null terminator in the buffer. This can occur if H5Igetname is invoked in a way...

CVE-2026-26197

CVE-2026-26197 affects HDF5. A vulnerability arises when an HDF5 file is maliciously altered such that the array datatype’s full size, element count, and element size do not align (dt->shared->size, dt->shared->u.array.nelem, dt->shared->parent->shared->size). If these val...

CVE-2026-26197 Array full size, element count, and element size are not checked to make sure they match in H5Odtype.c

PYSEC-2026-2546 Keras has a Local File Disclosure via HDF5 External Storage During Keras Weight Loading

Summary TensorFlow / Keras continues to honor HDF5 “external storage” and ExternalLink features when loading weights. A malicious .weights.h5 or a .keras archive embedding such weights can direct loadweights to read from an arbitrary readable filesystem path. The bytes pulled from that path...
