CVE-2026-87825
7.7 ÉlevéeDescription
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.
