Research direction
Start by reading the linked OpenResty issue #1146 and tracing the ngx_http_lua_socket_tcp_finalize entry point, especially the receiveuntil userdata garbage-collection path described here. The issue does not name source files or tests; completion would require reproducing the heap-use-after-free, correcting its ownership or finalization handling, and adding regression coverage.
