Kerentanan Integer Overflow or Wraparound. Skor CVSS 3.1 8.2 (High) menurut vulncheck.com.

Deskripsi (NVD)

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.
