+Subject: [PATCH] Fix CVE-2025-15269: Use-after-free in SFD ligature parsing
+ (#5722)
+
+Prevent circular linked list in LigaCreateFromOldStyleMultiple by clearing
+the next pointer after shallow copy. The shallow copy propagates liga's
+modified next pointer from previous iterations, creating a cycle that
+causes double-free when the list is traversed and freed.
+
+Fixes: CVE-2025-15269 | ZDI-25-1195 | ZDI-CAN-28564
