0 A vulnerability in mod_cluster's AdvertiseListenerImpl (org.jboss.modcluster core module) allows a crafted UDP multicast datagram missing certain headers to cause a NullPointerException, terminating the advertise listener thread silently. This denial-of-service condition persists until the node is restarted and affects deployments even with configured security keys.

0 CVE-2026-76166 is a medium-severity vulnerability in Red Hat JBoss Enterprise Application Platform 7's mod_cluster component. A crafted UDP multicast datagram lacking certain HTTP headers triggers a NullPointerException in the advertise listener, causing the listener thread to terminate silently and persist until the node is restarted. This denial-of-service condition affects availability but does not impact confidentiality or integrity. The issue occurs even if a security key is configured. Mitigation involves disabling multicast-based proxy advertisement or isolating the multicast network segment.
