Until an official fix is available, avoid processing untrusted or incompressible data with the vulnerable Snappy.compress method to reduce risk.
Description
CVE-2026-93452 is a high-severity buffer overflow vulnerability in the snappy-java library up to version 1.1.10.8. The flaw occurs in the Snappy.compress(ByteBuffer, ByteBuffer) method, where an out-of-bounds write can happen if attackers supply incompressible data exceeding the destination buffer's capacity. This can corrupt off-heap memory and cause the Java Virtual Machine (JVM) to terminate unexpectedly.
