+title: Use-After-Free When Redefining SQLite Functions with Different Arity
+date: 2026-06-07
+description: |
+  ## Summary
+
+  Using Database#create_function or Database#define_function to define
+  the same function name more than once with different numbers of
+  arguments ("arity") or text encodings will result in a invalid memory
+  read and a segmentation fault.
+
+  ## Severity
+
+  The sqlite3-ruby repo maintainers assess this as Low severity. It is
+  reliably triggered after GC when code is structured in a particular way.
+  There is no known general exploit that could be used as a denial
+  of service attack.

+title: Use-After-Free in SQLite Aggregate Function Callbacks
+date: 2026-06-07
+description: |
+  ## Summary
+
+  Using Database#create_aggregate, #create_aggregate_handler, or
+  Database#define_aggregator to define an aggregate function, and
+  then using an open statement calling that function after the database
+  has been explicitly closed will result in an invalid memory read
+  and a segmentation fault.

+
+  The sqlite3-ruby repo maintainers assess this as Low severity. It is
+  reliably triggered after GC when code is structured in a particular way.
