CVE-2026-116590: snappy-java: JVM crash from unchecked ranges in Snappy.arrayCopy and SnappyOutputStream.rawWrite
Snappy.arrayCopy(Object src, int offset, int byteLength, Object dest, int destOffset) called a native memcpy without validating the ranges. A negative or oversized byteLength or offset read or wrote outside the arrays and crashed the JVM. SnappyOutputStream.rawWrite and SnappyInputStream.rawRead, and therefore the typed-array write/read methods, pass caller-supplied ranges to this method.
