No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A use-after-free security issue exists in the server's query execution memory tracking subsystem. An authenticated user with read privileges can trigger a write to freed heap memory through a sequence of standard database commands, leading to server process crash or potential memory corruption. No user interaction is required.
