+Subject: [PATCH] Fix CVE-2025-2925 (#5739)
+
+This PR fixes issue #5383, which was occurring due to actual_len + H5C_IMAGE_EXTRA_SPACE being 0. When realloc was called, it freed image, but gets sent to done before new_image can be assigned to image. Because the pointer for image isn't null, it attempts to free it here again, causing the double free to occur. This PR addresses Quincey's concern and fixes the issue while preserving new_image and image.
+
+The bug was first reproduced using the fuzzer and the POC file from #5383. With this change, the double free no longer occurs.
+
+CVE: CVE-2025-2925
+Upstream-Status: Backport [https://github.com/HDFGroup/hdf5/commit/4310c19608455c17a213383d07715efb2918defc]
