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.

CVE-2026-17572 [MEDIUM] CWE-787 hdf5: HDF5: Denial of Service via crafted file requiring user interaction
hdf5: HDF5: Denial of Service via crafted file requiring user interaction
A flaw was found in HDF5, a data management library. This vulnerability, a heap-based buffer overflow, allows a local attacker to cause a denial of service (DoS) by persuading a user to open a specially crafted HDF5 file. The malformed file can trigger out-of-bounds memory operations, leading to application crashes or instability.
Statement: This Moderate impact vulnerability in HDF5 requires user interaction to process a specially crafted HDF5 file, limiting the attack vector to local scenarios. Successful exploitation can lead to a denial of service. The HDF5 library is used in Red Hat Enterprise Linux AI, Red Hat AI Inference Server, and Red Hat OpenShift AI.
