CVE-2025-7068Public exploit

Service degradation via unreleased metadata cache entries

Published Jul 4, 2025 · Updated Jul 8, 2025

Memory leak in HDF5 1.14.6 allows local users to degrade service availability by supplying a crafted HDF5 file to a local process. During metadata-cache discard failures, H5C__flush_single_entry skips the free_icr callback, leaving H5FL__malloc allocations and pinned entries unreleased. Exploitation requires local low-privileged access and repeated processing can prevent the metadata cache from flushing and closing.
