Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

snappy-java versions before 1.1.10.9 are affected. Snappy.arrayCopy and the stream write and read methods pass unchecked offsets and lengths to a native memcpy, so a negative or oversized value can read or write outside array bounds and crash the JVM. Upgrade to 1.1.10.9, or validate offsets and lengths before calling these methods.

Written 2 Nov 2026.
