CVE-2026-93452: Out-of-bounds Write in xerial snappy-java
CVE-2026-93452 is a high-severity buffer overflow vulnerability in the snappy-java library (up to version 1.1.10.8). It occurs in the Snappy.compress(ByteBuffer, ByteBuffer) method, where writing past the end of the destination buffer can corrupt off-heap memory and cause the Java Virtual Machine (JVM) to terminate. This happens when attackers supply incompressible data exceeding the destination buffer's remaining capacity.
AI Analysis
Technical Summary
The vulnerability CVE-2026-93452 affects snappy-java versions up to 1.1.10.8. It is a buffer overflow in the Snappy.compress(ByteBuffer, ByteBuffer) function, which writes beyond the destination buffer boundary when processing incompressible data that exceeds the buffer's remaining capacity. This leads to off-heap memory corruption and JVM termination. The CVSS 4.0 score is 8.7, indicating high severity, with no required privileges or user interaction for exploitation.
Potential Impact
An attacker can cause a denial of service by crashing the JVM through off-heap memory corruption. This disrupts applications using the vulnerable snappy-java library for compression. There is no indication of code execution or data leakage from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted or incompressible data with the vulnerable Snappy.compress method to reduce risk.
