+.{elastic-defend}'s network driver may lead to bug checks
+[%collapsible]
+====
+*Details* +
+On July 8, 2025, a known issue was discovered in {elastic-defend}'s network driver that may lead to kernel pool corruption, resulting in bug checks (BSODs) on Windows systems with a large number of long-lived network connections that remain inactive for 30+ minutes.
+
+The system may bug check with any of a variety of codes such as `SYSTEM_SERVICE_EXCEPTION` or `PAGE_FAULT_IN_NONPAGED_AREA`.
+
+For more information, check https://github.com/elastic/endpoint/issues/90[#90]
+
+*Workaround* +
+Downgrade to 8.17.7 or install 8.17.9 once it becomes available.
+
+If you're unable to upgrade or downgrade, set the `advanced.kernel.network` advanced setting to `false` in your {elastic-defend} integration policy.
