+Subject: [PATCH] Fix CVE-2025-2915 (#5746)
+
+This PR fixes issue #5380, which has a heap based buffer overflow after H5MF_xfree is called on an address of 0 (file superblock).
+This PR changes an assert making sure addr isn't 0 to an if check.
+
+The bug was first reproduced using the fuzzer and the POC file from #5380. With this change, the heap based buffer overflow no longer occurs.
