+title: Use-After-Free in SQLite Aggregate Arguments in
+  Heap-Allocated Argument Array
+date: 2026-08-11
+description: |
+  ## Summary
+
+  Using Database#create_aggregate, #create_aggregate_handler, or
+  Database#define_aggregator to define an aggregate function that takes
+  two or more arguments, and then evaluating it over TEXT or BLOB column
+  values, can free the Ruby objects holding those arguments while a
+  later argument is still being converted, during ordinary garbage
+  collection. The aggregate's step method then receives an incorrect
+  object, or the process crashes with a segmentation fault.
