NVD Description

Note: Versions mentioned in the description apply only to the upstream zstd-jni package and not the zstd-jni package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

zstd-jni before 1.5.7-14 contains a use-after-free vulnerability where streams and contexts hold a dictionary's shared lock only during the load call, allowing the dictionary to be closed while still referenced. Attackers can close a dictionary after associating it with a stream or context, causing subsequent read or write operations to access freed native memory, resulting in silent data corruption or JVM crashes.
