There is no fixed version for RHEL:10 hdf5.

NVD Description

Note: Versions mentioned in the description apply only to the upstream hdf5 package and not the hdf5 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
