Process crash or code execution via out-of-bounds read
Published May 9, 2024 · Updated Feb 13, 2025
Out-of-bounds read in HDF5 1.14.3 and earlier allows attackers to crash a process or potentially execute code via crafted data. H5FL_arr_malloc reads beyond an allocation boundary while servicing H5S_set_extent_simple during dataspace extent handling. Exploitation requires an application or tool to process attacker-controlled HDF5 data; upstream release notes describe this flaw class as file-parsing errors that generally cause segmentation faults.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
