CVE-2022-21294: Medium severity IBM Security Guardium vulnerability
An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
Other sources
It was discovered that the implementation of the IdentityHashMap class in the Libraries component of OpenJDK did properly validate the value of its size attribute when creating object instance from a serialized form. A specially-crafted input could cause a Java application to use an excessive amount of memory when deserialized.
