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 num_messages count exceeding list_max, triggering out-of-bounds heap reads and writes in H5SM__cache_list_deserialize and H5SM__cache_list_verify_chksum.

Summary		(es) Desbordamiento de búfer basado en montículo en el código de deserialización del índice de lista SOHM en HDF5 hasta la versión 2.1.1 en todas las plataformas permite a los atacantes causar una denegación de servicio (caída) mediante un archivo HDF5 manipulado cuyo índice de lista de mensajes compartidos declara un recuento de num_messages que excede list_max, desencadenando lecturas y escrituras de montículo fuera de límites en H5SM__cache_list_deserialize y H5SM__cache_list_verify_chksum.
