This vulnerability impacts a server that supports the wildfly-http-client protocol. Whenever a malicious user opens and closes a connection with the HTTP port of the server and then closes the connection immediately, the server will end with both memory and open file limits exhausted at some point, depending on the amount of memory available. \r\n\r\nAt HTTP upgrade to remoting, the WriteTimeoutStreamSinkConduit leaks connections if RemotingConnection is closed by Remoting ServerConnectionOpenListener. Because the remoting connection originates in Undertow as part of the HTTP upgrade, there is an external layer to the remoting connection. This connection is unaware of the outermost layer when closing the connection during the connection opening procedure. Hence, the Undertow WriteTimeoutStreamSinkConduit is not notified of the closed connection in this scenario. Because WriteTimeoutStreamSinkConduit creates a timeout task, the whole dependency tree leaks via that task, which is added to XNIO WorkerThread. So, the workerThread points to the Undertow conduit, which contains the connections and causes the leak.\n\n## Affected\n\n- `active_iq_unified_manager`\n- `oncommand_workflow_automation`\n- `fuse = 1.0`\n- `integration_camel_for_spring_boot`\n- `jboss_enterprise_application_platform = 7.4`\n- `openshift_container_platform = 4.11`\n- `openshift_container_platform = 4.12`\n- `openshift_container_platform_for_linuxone = 4.9`\n- `openshift_container_platform_for_linuxone = 4.10`\n- `openshift_container_platform_for_power = 4.9`\n- `openshift_container_platform_for_power = 4.10`\n- `single_sign-on`\n- `single_sign-on = 7.6`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2025:4226** · Red Hat · fixed in: Red Hat JBoss Enterprise Application Platform 7.1 EUS for RHEL 7 Server · released 2025-04-28 · [advisory](https://access.redhat.com/errata/RHSA-2025:4226)\n- **RHSA-2025:9583** · Red Hat · fixed in: Red Hat JBoss Enterprise Application Platform 7.3 EUS for RHEL 7 Server · released 2025-06-25 · [advisory](https://access.redhat.com/errata/RHSA-2025:9583)\n- **RHSA-2024:1674** · Red Hat · fixed in: Red Hat JBoss EAP 7.4 for RHEL 7 Server · released 2024-04-04 · [advisory](https://access.redhat.com/errata/RHSA-2024:1674)\n- **RHSA-2024:1860** · Red Hat · fixed in: Red Hat Single Sign-On 7.6 for RHEL 7 Server · released 2024-04-16 · [advisory](https://access.redhat.com/errata/RHSA-2024:1860)\n- **RHSA-2024:1675** · Red Hat · fixed in: Red Hat JBoss EAP 7.4 for RHEL 8 · released 2024-04-04 · [advisory](https://access.redhat.com/errata/RHSA-2024:1675)\n- **RHSA-2024:1864** · Red Hat · fixed in: Middleware Containers for OpenShift · released 2024-04-16 · [advisory](https://access.redhat.com/errata/RHSA-2024:1864)\n- **RHSA-2024:1861** · Red Hat · fixed in: Red Hat Single Sign-On 7.6 for RHEL 8 · released 2024-04-16 · [advisory](https://access.redhat.com/errata/RHSA-2024:1861)\n- **RHSA-2024:1676** · Red Hat · fixed in: Red Hat JBoss EAP 7.4 for RHEL 9 · released 2024-04-04 · [advisory](https://access.redhat.com/errata/RHSA-2024:1676)\n- **RHSA-2024:1862** · Red Hat · fixed in: Red Hat Single Sign-On 7.6 for RHEL 9 · released 2024-04-16 · [advisory](https://access.redhat.com/errata/RHSA-2024:1862)\n- **RHSA-2024:1866** · Red Hat · fixed in: RHSSO 7.6.8 · released 2024-04-16 · [advisory](https://access.redhat.com/errata/RHSA-2024:1866)\n- **RHSA-2024:3354** · Red Hat · fixed in: Red Hat Fuse 7.13.0 · released 2024-05-23 · [advisory](https://access.redhat.com/errata/RHSA-2024:3354)\n- **Red Hat VEX** · Important · affected: Red Hat build of Apache Camel for Spring Boot 4, Red Hat JBoss Data Grid 7, Red Hat JBoss Fuse Service Works 6, Red Hat Process Automation 7 · no fix planned: Red Hat JBoss Data Grid 7, Red Hat JBoss Fuse Service Works 6, Red Hat Process Automation 7, Red Hat build of Apache Camel for Spring Boot 4 · updated 2026-10-02 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2024/cve-2024-1635.json)","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":41.3,"likelihood":0.9,"exploitation":0,"ransomware":0},"changes":[]}
