CVE-2026-40943: CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in oxia-db oxiaCVE-2026-40943 0 CVE-2026-40943 is a race condition vulnerability in oxia, a metadata store and coordination system, affecting versions prior to 0. 16. 2. The issue arises from improper synchronization between session heartbeat processing and session closure, causing the server to panic due to sending on a closed channel or deadlock scenarios. This is triggered by the heartbeat() method using a blocking channel send while holding a mutex, which under certain timing conditions with concurrent close() calls leads to a time-of-check to time-of-use (TOCTOU) gap. The vulnerability has a high severity score of 8. 7. A fix is available in version 0. 16. 2. Join the discussion | CVE Database V5 | 04/21/2026, 21:13:31 UTC Added: 04/21/2026, 21:16:06 UTC |
