Hi,

The following vulnerability was published for zstd-jni-java.

CVE-2026-90560[0]:
| zstd-jni versions 1.2.0 through 1.5.7-13 contain an out-of-bounds
| read vulnerability in the ZstdDictDecompress constructor because
| offset and length arguments are never validated against the
| dictionary array bounds. Attackers can supply arbitrary offset or
| length values to read memory past the end of the supplied array,
| potentially causing JVM termination.
