Fixed In Version:		Doc Type:	---
Doc Text:	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.

Description OSIDB Bzimport 2026-09-09 14:52:45 UTC

zstd-jni versions before 1.5.7-14 fail to validate closed state in setDict, setLongMax, setLevel and setRefMultipleDDicts methods of stream classes. Attackers can call these methods on closed streams to write through freed native pointers, corrupting unrelated objects or crashing the JVM.
