CVE-2026-15567 is a denial-of-service vulnerability in Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7. It arises from a flaw in Wildfly's CSIv2Util component, where an attacker can trigger an OutOfMemoryError by sending a maliciously crafted GSS token with an attacker-controlled length field that lacks bounds checking. This vulnerability allows a remote unauthenticated attacker to cause a denial of service without impacting confidentiality or integrity.

A flaw was found in Wildfly. A remote unauthenticated attacker can trigger OutOfMemoryError as CSIv2Util's GSS token decoder reads an attacker-controlled length field without bounds checking and attempts to allocate a byte array of that size.
