+Subject: [PATCH] Refix of the attempts in PR-5209 (#5722)
+
+This PR addresses the root cause of the issue by adding a sanity-check immediately
+after reading the file space page size from the file.
+
+The same fuzzer in GH-5376 was used to verify that the assert before the vulnerability
+had occurred and that an error indicating a corrupted file space page size replaced it.
+
+CVE: CVE-2025-2914
+Upstream-Status: Backport [https://github.com/HDFGroup/hdf5/commit/804f3bace997e416917b235dbd3beac3652a8a05]
