Lifecycle Timeline
7DescriptionCVE.org
A vulnerability, which was classified as problematic, has been found in HDF5 1.14.6. This issue affects the function H5FL__malloc of the file src/H5FL.c. The manipulation leads to memory leak. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used.
AnalysisAI
Memory leak in HDF5 1.14.6's H5FL__malloc function allows local attackers with low privileges to degrade system availability by exhausting memory resources. A public exploit exists, and a vendor patch is available; no active exploitation has been confirmed.
Technical ContextAI
The flaw resides in the H5FL__malloc function within src/H5FL.c, part of HDF5's internal memory management. It is classified as CWE-401 (Missing Release of Memory after Effective Lifetime). The affected product is HDF5 1.14.6, identified by CPE cpe:2.3:a:hdfgroup:hdf5:1.14.6.
RemediationAI
Upgrade to a patched release of HDF5; the vulnerability was addressed in a later version (exact fix version not specified in advisory). Monitor the HDF Group issue #5578 for details. As a temporary measure, restrict local access to HDF5-linked applications or disable processing of untrusted HDF5 data, though this may only reduce exposure given the local attack vector.
