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.MIN VALUE to read unmapped memory, causing JVM termination or extracting arbitrary frame size data from unintended memory locations.
