CVE-2026-93564: Red Hat Amq Broker 7

High severity, CVSS 7.5. EPSS: 0.9% chance of exploitation in the next 30 days.

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.
