CVE-2026-40943

Description
Oxia is a metadata store and coordination system. Prior to 0.16.2, a race condition between session heartbeat processing and session closure can cause the server to panic with send on closed channel. The heartbeat() method uses a blocking channel send while holding a mutex, and under specific timing with concurrent close() calls, this can lead to either a deadlock (channel buffer full) or a panic (send on closed channel after TOCTOU gap in KeepAlive). This vulnerability is fixed in 0.16.2.
