CVE-2026-92627: Use After Free
A heap-use-after-free vulnerability exists in H5Tconvff in src/H5Tconv.c in HDF5 before 1.14.2. When converting a compound datatype containing floating-point members during a dataset read, a temporary buffer allocated with calloc is freed and subsequently read from within the same conversion...

Name of the Vulnerable Software and Affected Versions HDF5 versions prior to 1.14.2 Description A heap-use-after-free issue exists in the H5T conv f f function within src/H5Tconv.c. This occurs during the conversion of a compound datatype containing floating-point members during a dataset read,...
hdf5: HDF5 h5dump: Arbitrary code execution via a crafted HDF5 file
A flaw was found in the HDF5 software, specifically in the h5dump helper utility. An attacker can exploit this vulnerability by providing a specially crafted HDF5 file, leading to a heap-use-after-free condition. This flaw can result in arbitrary code execution, allowing the attacker to take...
CVE-2026-19023
A flaw was found in HDF5. The h5dump tool, used for dumping HDF5 file contents, is vulnerable to an untrusted pointer dereference. An attacker could craft a malicious HDF5 file containing a variable-length string dataset. When this file is processed in binary output mode, it can lead to a denial ...
EUVD-2026-53659
Untrusted pointer dereference in the renderbinoutput function in the h5dump tool in HDF5 before 2.1.1 allows attackers to cause a denial of service via a variable-length string dataset with more than one element dumped in binary mode, which corrupts the per-element stride calculation and causes...
