Doc Type: ---
Doc Text:
A memory leak flaw was found in WildFly in all versions up to 21.0.0.Final, where the host-controller tries to reconnect in a loop, generating new connections that are not properly closed while unable to connect to the domain controller. This flaw allows an attacker to cause an Out of memory (OOM) issue, leading to a denial of service. The highest threat from this vulnerability is to system availability.
