CVE-2023-23205Public exploit

Local memory consumption via unreleased ASDU allocation

Published Feb 24, 2023 · Updated Mar 12, 2025

Memory leak in lib60870 2.3.2 allows local users to consume unreleased memory when the example multi-client server exits. At line 213, main assigns a CS101_ASDU_create allocation to newAsdu but never releases that object before shutdown. The published Ctrl+C reproduction requires local process control and demonstrates one 296-byte leak at exit, not sustained remote exhaustion.
