SUSE CVE-2026-87823

zstd-jni before 1.5.7-14 performs 32-bit signed bounds checks on three direct-ByteBuffer frame-size native methods, allowing out-of-bounds memory reads via negative or overflowing offsets. Attackers can supply negative offset values near Integer.MINVALUE to read unmapped memory, causing JVM...

SUSE CVE-2026-87824

zstd-jni before 1.5.7-14 fails to validate the samples buffer capacity in Zstd.trainFromBufferDirect, allowing attackers to read past buffer boundaries by supplying oversized per-sample lengths. Attackers can trigger out-of-bounds memory access by providing crafted sample length arrays that cause...

SUSE CVE-2026-87825

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, causi...

SUSE CVE-2026-87877

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...

CVE-2026-87823

A flaw was found in zstd-jni. This vulnerability arises from insufficient bounds checks in direct-ByteBuffer frame-size native methods, which allows attackers to provide negative or overflowing offsets. A remote attacker can exploit this by supplying specially crafted negative offset values,...
