What is CVE-2026-93452?

The snappy-java library, through version 1.1.10.8, has a critical buffer overflow vulnerability within the Snappy.compress(ByteBuffer, ByteBuffer) method. This flaw allows attackers to input incompressible data which can surpass the remaining capacity of the destination buffer. Consequently, this could lead to memory corruption outside the heap and could terminate the Java Virtual Machine (JVM). Proper awareness of this vulnerability is essential to prevent potential exploitation.
