CVE-2026-87823

zstd-jni (Java JNI binding for Zstandard compression) versions 1.1.1 through 1.5.7-13 are vulnerable to an out-of-bounds read caused by 32-bit signed bounds checks in three direct-ByteBuffer frame-size native methods. An attacker can supply negative offset values near Integer.MIN_VALUE , causing ...

CVE-2026-87823 zstd-jni 1.1.1 through 1.5.7-13 Out-of-Bounds Read via Direct ByteBuffer Frame-Size Methods

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...

CVE-2026-87795

A flaw was found in zstd-jni. This vulnerability occurs due to insufficient validation of offset and length parameters within the ZstdDictCompress constructor. An attacker can exploit this by providing untrusted values, leading to an out-of-bounds memory read. This can result in the disclosure of...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read due to the ZstdDictCompressbyte dict, int offset, int length, int level constructor in ZstdDictCompress.java. An attacker can trigger a native heap read, crash the JVM, or leak adjacent memory by supplying a negative...
