DescriptionCVE.org

A vulnerability, which was classified as problematic, was found in HDF5 1.14.6. Affected is the function H5O__chunk_protect of the file /src/H5Ochunk.c. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used.

AnalysisAI

Heap-based buffer overflow in HDF5 1.14.6 allows local attackers with low privileges to cause denial of service via crafted input to the H5O__chunk_protect function. A public exploit is available, though no active exploitation (CISA KEV) has been confirmed. The vulnerability is rated low severity due to local access requirements and limited impact to availability only.
