Summary
A flaw was found in zstd-jni. An attacker could exploit a use-after-free vulnerability by calling specific methods on closed streams without proper validation.
This could lead to memory corruption, potentially allowing the attacker to corrupt unrelated objects or cause the Java Virtual Machine (JVM) to crash, resulting in a denial of service. The vulnerability can allow memory corruption or denial of service when specific stream methods are called after the stream has been closed.

Mitigation checklist
- No complete workaround is currently available. As a temporary measure, applications using zstd-jni should not call setDict(), setLongMax(), setLevel(), or setRefMultipleDDicts() on a stream after close(). Upgrade to a Red Hat product release containing zstd-jni 1.5.7-14 or later when available.
