      <link>https://vulnerability.circl.lu/vuln/cve-2026-93564</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Red Hat AMQ Broker 7, Red Hat build of Apache Camel 4 for Quarkus 3, Red Hat build of Apache Camel for Spring Boot 4, Red Hat build of Apicurio Registry 3, Red Hat build of Debezium 3, Red Hat Build of Keycloak, Red Hat Fuse 7, Red Hat JBoss Enterprise Application Platform 7, Red Hat Single Sign-On 7&lt;/p&gt;
&lt;p&gt;A flaw was found in Netty. A reference-count leak in the HAProxy PROXY-v2 message decoder allows a remote, unauthenticated attacker to send specially crafted PROXY-protocol v2 headers. This can lead to memory exhaustion, resulting in a Denial of Service (DoS) for the affected system.&lt;/p&gt;</description>
