CVE-2026-17574

A flaw was found in HDF5. A local user can exploit this vulnerability by processing a specially crafted HDF5 file. This file, containing an attribute with an invalid variable-length datatype, can cause a NULL pointer dereference, leading to an application crash and resulting in a denial of servic...

DEBIAN-CVE-2026-17572

Heap-based buffer overflow in the SOHM list-index deserialization code in HDF5 through 2.1.1 on all platforms allows attackers to cause a denial of service crash via a crafted HDF5 file whose shared-message list index declares a nummessages count exceeding listmax, triggering out-of-bounds heap...

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...

EUVD-2026-45969

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...

JLSEC-2026-770 OSGeo GDAL vulnerable to out-of-bounds read

A weakness has been identified in OSGeo gdal up to 3.13.0dev-4. The affected element is the function GDfieldinfo of the file frmts/hdf4/hdf-eos/GDapi.c. Executing a manipulation can lead to out-of-bounds read. The attack needs to be launched locally. The exploit has been made available to the...

Keras: HDF5 virtual datasets can disclose local files

Keras versions up to and including 3.13.2 are vulnerable to an arbitrary HDF5 file read due to an incomplete fix for CVE-2026-1669. The vulnerability resides in the H5IOStore.verifydataset and fileeditor.py methods, which fail to check the dataset.isvirtual property of HDF5 datasets. This allows ...
